摘要: 采用三种方法验证飞机构型Euler绕流结构网格方法计算。第一,同一网格,采用不同的方法或程序进行计算;采用Jameson中心差分有限体积方法和Steger-Warming流量分裂迎风格式有限体积方法,为计算提供容错手段;第二,网格细化和网格点重新分布,并通过网格收敛指标进行评估;第三,提出新的多块拼接网格拓扑,采用不同的网格拓扑进行计算。

关键词: 计算流体力学, 可信度, 多块拼接网格, 有限体积法

Abstract: Three approaches are suggested to verifty the Euler flow calcuations for aircraft configurations.The first proposed approach is to calculate the same flow problem on the same grid with different methods, which uses,Jameson's central-difference finite volume method and Steger-Warming's flux-splitting finite volume method.The second one is to evaluate the effects of grid refinements by using Roache's Grid Convergence Index.And the third one is to calculate the same flow problem on grids with different topology.The computed results are validated by comparisons with authoritative and credible experimental data.

Key words: Computational Fluid Dynamics, credibility, multi-block grid, finite volume method
