The primary objective of this workshop is to delve into recent advancements and future challenges in sustainable aerospace technology. The aerospace sector is experiencing significant growth in both aviation and […]
The intriguing annual migration of the dragonfly species, Pantala flavescens, was reported a century ago. The multi-generational, transoceanic migration circuit spanning 14000-18000 kms, from India to Africa is an astonishing feat for an insect few cms in size. Wind, precipitation, fuel, breeding, and the life cycle affect the migration, yet understanding of their collective role […]
The laminar to turbulent boundary layer transition onset has perplexed fluid dynamics community irrespective of the flow regime under which the phenomenon is probed. The complexity of the problem is compounded in high-speed compressible flows where in the transition onset location is a strong function of many subtle factors like freestream quality, surface roughness, wall […]
The dynamic behavior of structural components over broad frequency ranges, particularly thick beams under different constraints, is important in many engineering applications where reduced dimensional modeling is required for design. Applications are aerospace structures, mechanical systems and civil infrastructure. The rigid cross-section assumption in Euler-Bernoulli and even third-order beam theories cannot accurately capture the effects […]
Abstract: The presentation opens with a comparison of high-temperature materials with everyday metals. This will be followed by a discussion of challenges and an understanding of the machinability of high-temperature materials. Next, various strategies for machining high-temperature materials, along with practical real-life case studies, will be presented. We will be introducing the concept of Feed […]
Laser beam is highly affected by prevailing atmospheric conditions and limit the system performance for various applications. The talk mainly covers the cause of optical turbulence, its effects on laser beam and further discuss the technologies for controlling the beam for enhancing the effectiveness. Two main techniques namely the Tip-tilt correction for maintaining the beam […]
The transonic Mach number regime is a critical phase in the atmospheric ascent of launch vehicles, where aerodynamic loads peak due to the combined effects of high freestream dynamic pressure and angle of attack. Besides high steady loads, launch vehicles experience very high levels of pressure fluctuations caused by interactions between the unsteady λ-shock system […]
In this modern era, Space is vital for a Nation’s prosperity and without space, many critical functions would simply stop working. The increasing number of satellite launches in recent times, is congesting the space environment. Space is also becoming an increasingly contested environment from the perspective of non-civilian applications of satellites. The civilian and non-civilian […]
Miniaturised technologies, due to their portability, rapid responses, low powers and ability of multi-component integration, have received an ever-growing interest in areas like healthcare, air quality, and space research. This talk will provide an overview of my research in 3 domains of miniaturised technologies: a) microfluidics, b) MEMS sensors and c) nanoaerosol instruments. I will […]
Autonomous vehicles, such as unmanned aerial vehicles (UAVs) and autonomous mobile robots (AMRs), are at the forefront of technological innovation and are widely used across various applications. As these vehicles become more agile and operate primarily in unstructured environments, the components of the navigation pipeline must function in real time while optimizing limited onboard computing […]
Reducing greenhouse gas emissions from the transportation sector, especially carbon dioxide, is one of the main global challenges to achieve a more sustainable future. Developing internal combustion engines with advanced injection and combustion concepts that improve efficiency and decrease pollutant emissions are essential steps towards reducing their environmental impact. Over the past decades, flash-boiling injection […]
About fifty million people worldwide suffer from epilepsy, a neurological disorder marked by sudden, recurrent episodes of abnormal electrical activity in the brain, potentially causing sensory disturbances, convulsions and/or loss of consciousness. Seizure diaries that record the start and end times of each seizure, along with associated information are important in the management of the […]
