The results show the moment developing course of flow over flat wall and the evolvement of coherent structure , and also completely simulate all kinds of detail processes in development of boundary layer over flat wall , such as the generation and rise of low - speed stream , the extension and rupture of horse - hoof - shaped vortex and so on 模擬結(jié)果給出了平壁流動的瞬態(tài)發(fā)展過程以及流動中擬序結(jié)構(gòu)的發(fā)展演變過程,成功地模擬了平壁邊界層發(fā)展中的各種瞬態(tài)細(xì)節(jié)過程,如低速條帶的產(chǎn)生、上舉過程,馬蹄形渦的拉伸變形、破裂過程。
