A high-resolution hybrid scheme for solving three dimensional euler equations of high speed inlet flows

Abstract

A new and efficient three-dimensional implicit hybrid scheme for Euler equations is presented. The basic scheme is the coupling of the Jameson and Turkel’s LU decompositions and Prof. Zhang Hanxin’s NND concept. The improved LU decompositions are applied to discretize the implicit part of the Euler Equations and Zhang’s modified flux function to calculate the right hand side operators of the hybrid scheme. Numerical calculations were made of supersonic inlet flows with mixed external-internal compressions. Some of the computed results were compared with available wind tunnel data.
