摘要: 涡方法中粘性效应可通过涡的随机移动或改变涡核尺寸两种途径并入。本文侧重讨论后者。用改变涡核尺寸并入粘性的方法计算了Blasius平板同题,并与Blasius解做了比较。

Abstract: In the vortex method,the viscous effect can be incorporated by either random walk of the vortex or vortex aging. In this paper particular attention is paid to the latter, and the latter is applied to Blasius flat plate problem.Comparasion with Blasius's solution is made.
