Influence analysis on grid scale limiter of XY-SAS model

  • 摘要: XY-SAS(Xu & Yan Scale Adaptive Simulation)模型通过在SA(Spalart-Allmaras)模型耗散项的湍流尺度中引入基于平均涡量的冯卡门长度尺度,在不稳定流动区域具有类似LES(Large Eddy Simulation)的计算性能,且不存在DES(Detached Eddy Simulation)方法中RANS(Reynolds Averaged Navier-Stokes)与LES的交界面问题.由于SAS类模型预测的湍流能谱存在高波数衰减不足的缺陷,需要进一步在湍流尺度中引入网格尺度作为限制器.采用不同形式的网格尺度限制器构造了3种XY-SAS模型,对Re=3 900的圆柱绕流进行数值模拟,并与DES及实验数据进行比较.结果表明网格尺度限制器对XY-SAS模型的计算性能有较大影响,以最小网格间距作为高波数衰减限制器是较为合理的选择,此时模型对于大分离流动能够达到DES的模拟能力.
