Abstract:

Vortex-dominated flows are in abundance in engineering applications and natural environment. Vortical structures influence not only the flow field but also have major implications on forces and moments experienced by objects as well as noise generated by them. In this talk, I will present results from work carried out in my group across different projects. We will focus on at least two case studies. The first is aimed at understanding the aerodynamic and aeroacoustics performance of stalled wings while the second will focus on swimming efficiency of marine reptiles in Mesozoic era. These case studies will show that the behaviour of vortex interactions have a profound impact well beyond their specific application and that understanding these interactions can spawn new applications in varied areas including flow manipulation and bio-inspired vehicle design.
