This paper provides an accurate and robust hybrid fluctuation splitting scheme for the two-dimensional compressible Euler equations. The approach switches from a linear matrix LDA scheme in subsonic flow regions to a nonlinear scaler PSI scheme in supersonic ones. The method provides second-order-accurate solutions for subsonic, transonic and supersonic flows, captures shocks monotonically, and does not encounter any convergence difficulty.

Abstract

This paper provides an accurate and robust hybrid fluctuation splitting scheme for the two-dimensional compressible Euler equations. The approach switches from a linear matrix LDA scheme in subsonic flow regions to a nonlinear scaler PSI scheme in supersonic ones. The method provides second-order-accurate solutions for subsonic, transonic and supersonic flows, captures shocks monotonically, and does not encounter any convergence difficulty.
