The longest known insect migration: Fusing Biology with Aerospace Engineering for innovative solutions

STC Seminar Hall, Dept. of Aerospace Engineering

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 […]

Ph.D.(Engg): Investigations on Hypersonic Laminar to Turbulent Boundary Layer Transition in a Shock Tunnel.

STC Seminar Hall, Dept. of Aerospace Engineering

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 […]

MTech(Res) : Elastic Wave Dispersion Analysis and Mode Shape Investigation of Higher-order Beam Theory for Thick Beams

Online
Virtual Event Hybrid Event

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 […]
