Abstract

An efficient CFD approch based on higher order accurate numerical schemes has been developed for simulating unsteady hypersonic viscuous flows strongly associated with shock-shock interferernce flow phenomena. The principal concept of the present approach is to employ the higher-resolution finite difference schemes based on the fourth-order accurate compact MUSCL TVD scheme coupled with the AUSM-based scheme in space discretization and based on the maximum second-order accurate LU-SGS scheme modified using the Newton iteration in time integration. The hypersonic shock-shock interference flow which is well known as the Type IV is numerically investigated. The obtained numerical results re showing extremely complicatd flow structures, such as an unsteady supersonic jet, a jet-bow-shock, and unsteady supersonic shear layers. The reliability of the calculated results is checked by comparison with the existing experimental and numerical results.
