SUMMARY:M.Tech(Res) : Effect of hydrogen-enrichment on soot formation in laminar gaseous hydrocarbon flames
DESCRIPTION:Gaseous and particulate pollutants pose a significant threat to human health and the environment\, prompting regulatory action to address major sources of emissions. Soot is a key particulate pollutant. Recently\, emission standards for commercial aeroengines have been revised\, necessitating the mitigation of soot emissions. Investigating the soot formation process is a key step towards reducing emissions. Soot formation is a complex process that poses a challenge to the chemical kinetics community. Predicting soot is computationally expensive and challenging\, requiring reliable reduced mechanisms for practical fuels. The primary obstacle is the lack of systematic data to develop and validate chemical kinetics models for soot prediction. Hydrogen (H2) is being explored as a means to decarbonize the automotive\, aviation\, and power generation sectors. However\, implementing pure H2 in practical devices is difficult due to higher operating temperatures and flame speeds. Alternatively\, H2 can be blended into traditional hydrocarbon fuels. The addition of H2 influences the combustion chemistry of hydrocarbon fuels\, which consequently leads to changes in the composition of combustion products. The aviation industry uses practical fuels to form turbulent flames. However\, the complexity of practical fuels and flow fields makes it difficult to predict the concentrations of combustion emissions. A systematic study of soot formation in laminar gaseous-fuel flames can aid in developing reduced soot reaction mechanisms and understanding the soot formation process. This work reports a database of soot concentrations for C1–C4 hydrocarbons (methane\, ethane\, propane\, and butane) under laminar premixed and non-premixed conditions. Additionally\, the influence of H2 blending on soot formation is examined for these fuels. The parameters\, such as soot volume fraction (fv)\, distributions of soot precursors (PAH) and OH\, and gas temperature\, are measured using laser-based diagnostic techniques. The study of soot formation was performed on two different burner configurations: premixed and non-premixed. The premixed burner stabilized flames with φ = 2.3 were stabilized on the McKenna burner equipped with a stagnation plate. To ensure flame stability\, a mixture of O2 and Ar was used as the oxidizer. The reactant flow rates for test cases are selected such that the carbon influx (Cin)\, C/O ratio\, and O2 fraction in oxidizer are kept constant. The non-premixed flames were stabilized on a coflow burner. The flow conditions were selected to maintain a constant Cin\, thereby isolating the influence of Cin on soot. For both flame configurations\, H2 is added up to 40 % (by volume) to a base hydrocarbon fuel. H2 addition has three primary effects: thermal\, dilution\, and chemical. The chemical effect of H2 on soot is isolated using a reference flame\, created by replacing H2 with helium. The comparison of fv with this reference flame allows for the quantification of the chemical effect of H2 on soot. The fv is measured for both premixed and non-premixed flames by using the laser-induced incandescence (LII) technique. The distribution of PAH is measured using the planar laser-induced fluorescence (PLIF) technique. Additionally\, for non-premixed flames\, the distributions of OH and the temperature field were measured using the PLIF technique. The elemental carbon-to-hydrogen ratio (C/H) governs the maturity of soot. The soot maturity changes with height above the burner (HAB)\, introducing a bias in LII measurements. The LII fluence curve trends with HAB in premixed flames are used to estimate the relative change in soot maturity. These trends along HAB are used to estimate relative changes in the optical properties of soot particles (E(m)). PAH are the precursors to soot formation. However\, interpreting PAH-LIF (IPAH) trends is challenging due to the dependence of LIF on temperature and quenching by combustion products. In this work\, an empirical approach is used to correct the IPAH in premixed flames for these dependencies. Additionally\, the extinction signature in radial IPAH profiles is used to obtain absorption-based PAH concentration. This approach mitigates the bias in interpreting the PAH trends in premixed flames. Soot volume fraction (fv) increases monotonically with carbon number (C1 to C4) for alkanes in both laminar premixed and non-premixed flames. The total soot loading parameter is used to examine the overall sooting tendency. The soot loading decreases relative to neat flames with H2-enrichment for all fuels. The extent of suppression of soot formation by H2 addition is greater in premixed flames than in non-premixed flames. Cin is examined relative to CxHy/He flames. It was observed that Cin is strongly dependent on the type of fuel. H2 enrichment inhibits pyrolysis in ethylene (alkene) fuel\, contributing to delayed soot onset relative to the helium reference flame. Conversely\, H2 promotes (relative to helium) pyrolysis in non-premixed C1–C4 alkane flames\, thereby enhancing soot. In premixed alkane flames\, H2 suppresses soot in the inception-dominated region but enhances soot in growth-dominated regions. This contrasts with ethylene flame\, where H2 reduces soot formation throughout HAB. These findings reveal the fuel-specific impact of H2 enrichment on soot formation\, providing a systematic dataset to support the validation of chemical kinetics models and the design of low-emission combustion systems. The performance of the state-of-the-art soot reaction mechanism to predict fv is assessed against measurements. Additionally\, chemical kinetics analysis is performed to examine the chemical effect of H2 on soot formation. \n  \nSpeaker : Choudhari Aditya Sunil  \nResearch Supervisor :  Irfan Ahmed Mulla

SUMMARY:Experiments on a fluidic pinball: wake dynamics in the chaotic regime
DESCRIPTION:Over the past decade\, the fluidic pinball has become a valuable benchmarkfor studying flow control strategies. The configuration consists of three independently rotating cylinders positioned at the vertices of an equilateral triangle\, with the flow directed perpendicularly to one of its sides. The cylinder rotation rates serve as the control inputs\, while velocity sensors located in the wake provide the outputs. Despite its geometric simplicity\, the wake behind the fluidic pinball displays complex interactions of multiple frequencies and nonlinear dynamics\, making it an excellent test case for the development and evaluation of control laws. While numerous studies have been performed numerically at low Reynolds numbers\, experimental literature is limited\, mainly due to the associated engineering challenges. \nThis study presents the findings from wind tunnel experiments on a fluidic pinball in the chaotic regime (1333 ≤ Re ≤ 3333). Planar two-component particle image velocimetry (PIV) is employed to capture the velocity field while the velocity time traces are obtained from hot-wire anemometry and laser Doppler velocimetry (LDV). The stochastic bistable dynamics in the wake is characterized and its sensitivity to external disturbances is demonstrated. Coherent structures in the wake along with the associated temporal dynamics and their physical implications are analyzed for both the stationary pinball and the flow with steady\, open-loop forcing. The effect of blockage and evolution of 3D structures in the forced wake is discussed. A brief overview of the architecture set up for real-time control is also presented. \nSpeaker : Dr. Aditya Desai \nBiography : \nDr. Aditya Desai is a post-doctoral researcher at the Laboratory of Interdisciplinary Numerical Sciences (LISN)- CNRS\, Orsay\,France working towards Reinforcement Learning-based control of a fluidic pinball. He completed his Master’s and PhD from the Department of Aerospace Engineering\, IIT Kanpur. His research interests are in the domain of experimental aerodynamics\, reduced order modelling and flow control\,  wakes\, vortex induce vibration and sports aerodynamics. He completed his BTech in Aerospace Engineering at IITK in 2009. \n  \n

SUMMARY:Precision in Flow: Advances in PIV\, Hematology\, and High-Heat Flux Cooling for Power Dense Electronics
DESCRIPTION:This talk presents a comprehensive overview of advanced fluidic and thermal management strategies across biomedical and defense applications. We begin with a systematic evaluation of Particle Image Velocimetry (PIV)\, specifically addressing the challenges of simultaneous velocity and particle size measurement. By analyzing Gaussian intensity variations across the light sheet and the optical system’s depth of field\, we propose a balanced methodology for achieving consistent\, high-fidelity size estimates.\nBuilding on these measurement techniques\, we discuss phase-locked PIV studies conducted within a pulsatile flow loop of a ‘mitral’ model bileaflet mechanical heart valve (MHV). The localized jets\, steep velocity gradients\, and vortex recirculation zones identified in vitro provide critical correlations to in-vivo platelet aggregation\, highlighting the intersection of fluid mechanics and clinical pathology.\nThe discussion then shifts to the pivotal role of fluidic design in next-generation whole blood cell analyzers\, utilizing hydrodynamic focusing and sheath flow to optimize optical flow cell performance for hematology. Finally\, we conclude with a high-level summary of mission-critical work in energy storage and high-heat flux cooling. These technologies are essential for the thermal management of power-dense electronics and 3D Heterogeneous Integration (3DHI)\, ensuring reliability in the next frontier of microelectronic architecture.\n\nSpeaker : Dr. Ganesh Subramanian\n\n Biography:\nDr. Ganesh Subramanian is a technical leader and program/functional manager with over 20 years of experience bridging fundamental research and mission-critical engineering. An IISc Aerospace PhD and certified PMP/Agile professional\, he has led a diverse portfolio of high-priority energy storage and thermal management programs funded by the U.S. DoD and DARPA\, while at Teledyne Technologies. He has had a decade-long tenure\, each at Abbott and BD Biosciences\, developing fluidic and thermal subsystems for hematology instruments and flow cytometers. His career is grounded in high-impact fluid dynamics research working jointly with NASA and the Cleveland Clinic\, combining academic rigor with a proven track record of leadership in highly regulated defense and medical sectors.

SUMMARY:On Rayleigh Waves in Elastic Lattices
DESCRIPTION:A mathematical framework is presented to guide the search for Rayleigh waves in lattice materials based on periodic structure theory and the Bloch theorem. Architected materials with a periodic microstructure are distinguished from crystals in continuum anisotropic elasticity by the presence of at least one length scale and a band structure with partial and complete gaps for Bloch wave propagation. Non-affine bending deformations at or below the characteristic cell size are included by considering the unit cell as a framework of Timoshenko beams. We show that a quadratic eigenvalue problem\, with a Hermitian palindrome structure\, emerges from the force equilibrium and displacement compatibility relations for a propagating Bloch wave along any chosen orientation of the free edge/surface. Waves propagating along the free edge and penetrating to a finite depth into the medium are a partial set of eigensolutions of the nonlinear eigenproblem\, or its linearized symplectic form. These partial eigenwaves are used as the basis vectors to expand any arbitrary boundary displacements and force vectors\, which then constitute a complex asymmetric semi-infinite dynamic stiffness matrix. Surface and Rayleigh waves exist in its null space. Traction-free boundary conditions are used to show that the secular equation for Rayleigh waves is a real polynomial equation\, consistent with Stroh’s formulation for a length-scale independent anisotropic continuum crystal elasticity. Significant differences arising from the periodic structure are highlighted. Computational issues in the numerical solution of the structured eigenvalue problem for surface waves in lattices are addressed. Our formulation is applicable to any arbitrary lattice with complex unit cells and material architectures. Surface waves in a planar square lattice are found to emerge from the gaps for bulk waves in the band structure of the bulk waves. This research is a collaboration with Prof. N.A. Fleck of Cambridge University\, United Kingdom. \nSpeaker: Prof. Anasavarapu Srikantha Phani \nBiography: \nSrikanth is a tenured full professor at the University of British Columbia\, Vancouver\, Canada.
