Abstract
The space-time conservation element and solution element (CE/SE) scheme has caught many attention in aeroacoustic research community as an alternative numerical strategy for direct aeroacoustic simulation (DAS). As a result of its strict conversation of flow flux in both space and time, the low-order CE/SE scheme possesses excellent non-dissipative characteristics, expedient in calculating low Mach number DAS which requires uniform numerical accuracy to resolve the widely disparate flow and acoustic scales of the problem. In this paper, an attempt of validating a simplified Courant Number Insensitive CE/SE scheme using carefully selected aeroacoustic benchmark problems is reported. Excellent agreement with the benchmark results obtained firmly establishes that CE/SE scheme is a viable scheme for resolving the nonlinear physics of low Mach number aeroacoustic problems.
