free surface vortex

基本解釋

With given symmetric or asymmetric separation lines on the body surface, vortex strengths and free vortex locations are solved by an efficient iteration method presented by this paper.
通過(guò)給定物麪上對(duì)稱(chēng)或非對(duì)稱(chēng)的分離線(xiàn)位置，現(xiàn)在提出的算法有傚地解決了渦強(qiáng)度與自由渦線(xiàn)位置的疊代匹配問(wèn)題，首次得到了迎角大到60度的渦流數(shù)值解。
