F. A. Belolutskiy, V. V. Shepelev, S. V. Fortova ICAD RAS
Abstract:
The present paper is concerned with the analysis of WENO-schemes for the solution of
one-dimensional Euler equations with a Mie–Grüneisen type equation of state. The least
dissipative and oscillatory modifications of WENO-schemes in characteristic variables
with a monotonicity-preserving (MP) limiter are presented. A modified scheme, MP-WENO-SM, is developed, demonstrating the smallest amplitude of oscillations in the solution of the test problems with discontinuous initial data.
Keywords:
WENO, computational fluid dynamics, equations of state, shock waves in metals.
