Research

Focus on high fidelity simulations of unsteady flows with complex physical processes by using the Space-Time Conservation Element and Solution Element (CESE) method in conjunction with Beowulf cluster computers. Active research projects focus on numerical analyses of detonations, pulse detonation engine, cavitations, spray dynamics, and electro-magneto-gas-dynamics.
