Shear stress at the wall is a quantity of fundamental importance in wall-bounded flows. It determines skin-friction drag and the dynamics of flow separation. From an engineering standpoint, it is a key parameter which dictates the overall aerodynamic performance and structural loading of flight vehicles. Hence, there is a natural motivation for the development of […]
A comprehensive investigation of the energy and enstrophy cascade in physical space in a turbulent channel flow is presented for four Reynolds numbers. Bandpass filtering techniques are employed to isolate scales and quantify inter-scale interactions through kinetic energy flux, enstrophy generation, and enstrophy flux. Two bandpass filter formulations used in the literature are quantitatively assessed by comparing the output. The mean energy and enstrophy cascades are shown to be predominantly local for all the Reynolds numbers. Away […]
Multi-agent systems are increasingly deployed in missions involving large-scale tasks with complex objectives that are beyond the capability of a single agent. Such missions demand computationally efficient coordination strategies that ensure safety, reliable operation, and ease of implementation, particularly in dynamic and uncertain environments. This thesis investigates coordination strategies in multi-agent systems, specifically addressing the […]
Abstract: The Net Zero Emissions 2050 (NZE 2050) initiative sets an ambitious target to eliminate net CO2 within the next two decades. Achieving this goal demands widespread decarbonization across energy, transportation, residential, and industrial sectors. Carbon-free and carbon-neutral fuels are central to this effort. Hydrogen, an abundant, high-energy-density, carbon-free fuel is expected to play a […]
Hypersonic propulsion systems capable of sustained atmospheric flight are critical enablers for future reusable launch vehicles, long-range high-speed transport, and responsive global strike platforms. Among the various air-breathing concepts, scramjet engines offer unmatched efficiency at hypersonic speeds by utilizing atmospheric oxygen and avoiding the mass penalties associated with onboard oxidizers. However, the practical realization of […]
Air Marshal TD Joseph examines aerospace power as a critical instrument of statecraft, highlighting its strategic, coercive, and diplomatic roles in modern conflict and international relations. The latest example is India itself choosing aerospace power as the first instrument of choice to punish the enemy as in ‘Op Sindoor’. Drawing on historical and contemporary examples […]

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 […]
Bringing together the minds transforming emerging aerospace technologies into operational reality Featured Talks The Stratospheric Challenges for a High-Altitude Platform Dr. L Venkatrakrishnan, Chief Scientist and Program Director – HAP High Altitude Platforms (HAP) or High Altitude Pseudo Satellites which are unmanned aerial vehicles in the stratosphere are the next big challenge with applications […]
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 […]
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 […]
