Research Experience
Graduate Research Assistant
Virginia Tech - Blacksburg, VA

January 2015 - September 2018

 

  • Assessed the fish-tail flexibility effect on the propulsive efficiency of a fish by solving the coupled hydro-elastic problem between the tail and loads.

  • Postulated a new Lagrangian function from which we obtained the dynamics of unsteady point vortices shed from sharp edges of flat plate in arbitrary motion.

  • Solved the minimum time transition flapping wing micro-air vehicles (FWMAV) from hovering to forward flight, by integrating the body and wing dynamics of FWMAV through an optimal control framework ICLOCS and Matlab.

  • Developed the UVLM panel code (including leading-edge separation) in C++ and optimized the performance by using commands OpenMP and applying them to existing linear algebra solvers (LAPACK), efficient memory allocation and handling, and distributing the calculations on CPU's.

  • Obtained reduced order model for the unsteady aerodynamic loads on a finite wing by performing wind tunnel tests at Virginia Tech facilities.
