Research Interests

Aeroelasticity, Viscous Simulations, and Automatic Mesh Generation
My current areas of interest are aeroelastic simulations, viscous fluid flow work, and methods for automatic mesh generation. Currently I am involved in several projects which seek to couple Integral Boundary Layer solvers with Euler based fluid flow codes for the purpose of efficient aerodynamic design. Currently the methods are being implemented in SYN88, SYN87, and CART3D.
I have also been investigating methods for automatic mesh generation around arbitrary shape configurations. Complex configurations (such as high lift systems, automobiles, etc.) currently present immense difficulties to researchers in computational aerodynamics due to mesh generation problems. Programs like CART3D allow for solution of these configurations for the Euler equations. However, solutions for the Navier-Stokes equations require fine mesh resolution near the boundary, and cartesian methods often require a prohibitive number of cells to accurately resolve boundary layer effects. I am in the process of developing a solution to this problem by generating body-fitted unstructured meshes that have desirable orthogonality, smoothness, and cell volume properties. This algorithm is currently in its early stages, but the current methods look promising.
