Construction of shock stable scheme based on RoeM scheme

  • 摘要: Roe格式有着较高的黏性分辨率以及间断分辨率,但它在实际流动模拟时很容易出现激波不稳定现象.此外,它在无黏定常计算时无法保证总焓守恒.为了在保留Roe格式分辨率高的优点基础上改善其上述缺陷,将RoeM格式与高阶激波判别方法相结合,提出了RoeMW1,RoeMW2格式.计算结果表明,在流动较为简单的情况下提出的RoeMW1, RoeMW2 格式可以有效避免激波不稳定现象的出现且保持总焓守恒.而在一些较为复杂的流动结构计算中,虽然比之于RoeM格式均有所改善,但在RoeMW1基础上改进的RoeMW2格式在间断模拟时鲁棒性更强.
