Use of particle methods for understanding hypersonic shock boundary layer interactions

Abstract

The study of laminar, shock boundary layer interactions is performed using direct simulation Monte Carlo and linear stability theory for Edney type IV flows over a double wedge and a double cone. The high-fidelity time accurate simulations are shown to characterize the complex shock interactions of such flows as well as their unsteadiness. Comparison of bow shock oscillations and Kelvin-Helmholtz instabilities are found to be consistent with earlier values in the literature.The study of laminar, shock boundary layer interactions is performed using direct simulation Monte Carlo and linear stability theory for Edney type IV flows over a double wedge and a double cone.
