High Order Accuracy Methods for Supersonic Reactive Flows

Abstract

A multi-domain spectral method with stable and conservative penalty interface conditions for the numerical simulation of supersonic reactive recessed cavity flows with inhomogeneous grid is developed. The high order hybrid Spectral-WENO finite difference method under multi-domain framework is also introduced for the numerical solution of two dimensional nonlinear hyperbolic conservation laws in a Cartesian physical domain. A different approach in attempting to get more meaningful resultss is to model statistically those scales that can not be resolved. Methods for modeling those scales are being developed and applied. Numerical issues, such as boundary conditions, are being addressed and a new boundary procedure is being presented.
