| 摘 要： | 基于有限体积通量修正,应用了一类高阶迎风对流格式:二阶迎风格式、二次迎风插值格式、三次迎风插值格式及带TVD限制器的高分辨率格式,对于自然空泡湍流流动的数值计算方法进行了研究.计算模型为轴对称圆盘,计算结果表明所有高阶格式都能有效抑制一阶迎风格式产生的假扩散,并得到了更薄,更"透明"的汽-液界面,其中高分辨率TVD格式最好地捕捉到了空泡界面附近物理量的阶跃特性关键词: 自然空泡;高阶迎风对流格式;汽-液界面

| Abstract: | Based on flux correction, a class of Higher Order Convection Scheme including the second-order upwind difference scheme, the quadratic interpolation for convective kinematics, the cubic upwind interpolation scheme and high-resolution total variation diminishing schemes(TVD) were constructed to study the numerical method for the natural turbulent cavitating flows.They were applied and assessed for cavitating flows over an axisymmetric disk.The calculation results show that the high-order schemes can effectiv... |
