Skills
Accomplishments
- CFD Semester Project: Wrote a Computational Fluid Dynamics (CFD) program in C++ to solve for the flow in a square, lid-driven cavity using 2D, incompressible Navier-Stokes equations with time derivative preconditioning and artificial viscosity. The program used a Point Jacobi method with second-order accurate forward and central difference algorithms to advance the discretized equations forward in time with adaptive time stepping
- NASA Senior Design Project: First place in the National NASA Aeronautics Design Challenge 2019-2020. Participated in a small group to design a fully autonomous system to deliver package in an urban environment. Our Design, the RAAVEN, surpassed NASA’s expectations by providing a Systems Engineering perspective to aerial package delivery while leveraging our aeronautical expertise to design a superior product.
