About me
I am a Research Scientist/Engineer at Science and Technology Corporation, NASA
Ames Research Center, Moffett Field, CA. My primary research interest is in
the development and application of numerical methods to simulate fluid flows
pertaining to aerospace applications. Currently, my main project is on
developing high performance computational software for the design and analysis
of complex rotary wing systems.
In the recent past, I have worked on developing ALE embedded boundary framework for turbulent fluid-structure interaction problems. I was also involved in computational studies to understand the aerodynamics, and therefore to improve the productivity of wind turbines/farms. To ensure that numerical errors do not overwhelm the accuracy of these calculations, the errors were estimated and adaptively controlled using adjoint based methods.
Earlier, I have performed detailed analysis of the aerodynamics of
different micro air vehicle (MAV) configurations using CFD. This includes
simulation of unconventional rotary wing configurations like ducted and
cycloidal rotors along with studying avian-based flapping wing MAVs. I have
also extensively worked on improving connectivity algorithms for overset
(chimera) meshes and have applied them to simulate complex flow-field such as
those of helicopter rotors operating close to the ground.
