Numerical Framework for Aerospace Applications
We developed the highfidelity simulation framework for various aerospace applications ranging from subsonic to hypersonic flow regimes. The framework is based on stabilized and variational multiscale methods for fluid mechanics. The finite elements method (FEM) is used for discretization and special techniques (weak imposition of the Dirichlet boundary conditions and sliding interface formulation) is adopted to simulate complex flow behaviour.

Our group is currently working on extending the framework to the highspeed reacting flows, including the combustion modeling, and fluidthermalstructure interaction (FTSI).
