Flight in Nature and Engineering Using Unsteady Aerodynamics:

In these computational studies, Navier-Stokes equation is solved to understand the fundamentals of unsteady aerodynamics for insect/bird flights at low to moderate Reynolds numbers. Initial focus is on understanding the response and complex phase relationship of the flow field with the articulation of the associated aerodynamic surface. No effort has been made in these initial studies to include the elastic deformation of the aerodynamic surfaces. The main emphasis has been to obtain as high an accuracy as possible for the solution of incompressible flow.

A presentation was made at the international conference ICTACEM ( IIT Kharagpur, Dec '04) and a paper is under preparation based on activities so far:
