摘要
在文献[1,2]提出的一种低马赫数流动数值模拟新方法的基础上,本文作者进一步优化了算法,确定了该方法适用的马赫数范围,讨论了参数σ对计算的影响。大量的定常/非定常、低雷诺数/高雷诺数流动的计算结果表明这种方法具有计算精度高。
A new method, which does not pursue the divergence-free condition and decouples the energy equation from governing equations, is developed for low Mach number flows in Ref. On the basis of this new method, the authors further optimize the algorithm and determine some parameters. The appropriate Mach number range and numerical efficiency of the new method are also investigated. Some flow problems, including steady/unsteady flows around spheroid, are calculated to validate the new method. The results show that the new method has good efficiency and precision to compute complex flows .
