主 题:Shock capturing advection upwind splitting Euler equations weighted essentially non-oscillatory monotonicity preserving
摘 要:In this paper we demonstrate the accuracy and robustness of combining the advection upwind splitting method(AUSM),specifically AUSM+-UP[9],with highorder upwind-biased interpolation procedures,theweighted essentially non-oscillatory(WENO-JS)scheme[8]and its variations[2,7],and the monotonicity preserving(MP)scheme[16],for solving the Euler *** is found to be more effective than the three WENO variations ***+-UP is also shown to be free of the so-called“carbunclephenomenon with the high-order *** characteristic variables are preferred for interpolation after comparing the results using primitive and conservative variables,even though they require additional matrix-vector *** using the Roe flux with an entropy fix and the Lax-Friedrichs approximate Riemann solvers are also included for *** addition,four reflective boundary condition implementations are compared for their effects on residual convergence and solution ***,a measure for quantifying the efficiency of obtaining high order solutions is proposed;the measure reveals that a maximum return is reached after which no improvement in accuracy is possible for a given grid size.
