摘要
应用离散涡方法数值模拟了高雷诺数下的钝体 (圆柱、方柱等 )绕流 ,得到了流谱、涡谱等流动信息 .从流谱和涡谱中可以明显看到流动分离、旋涡以及旋涡随时间的发展演化 ,即成功模拟出流动所具有的非定常。
The flows past blunt (circle and square cylinder,etc) under high Reynoldes number are simulated numerically by using the Discrete Vortex Method,the streamline patterns and the distribution of vortices as well as other flow information are obtained.The nonlinear characteristics,such as the unsteady and unstable characteristics,are computed successfully.The flow separation and the consequential process of development of vortices are displayed clearly from the gained results.
