Numerical Framework for Aerospace Applications
We developed the high-fidelity simulation framework for various aerospace applications ranging from subsonic to hypersonic flow regimes. The framework is based on stabilized and variational multi-scale 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 high-speed reacting flows, including the combustion modeling, and fluid-thermal-structure interaction (FTSI).
