circumferential flow meaning in English

环流

Based on the numerical simulation for the large - diameter cylinder pile ' s 3d - circumferential flow under wave - flow co - function b using fvm , this paper analyzes the complicated 3d - torrent near the large - diameter cylinder pile , and gives the 3d - flow distribution , the stress distribution on the surface of cylinder pile and in the bed near the cylinder pile , furthermore , analyzes local scour of wave flow in the bed near the cylinder pile
摘要通过应用有限体积法对在波流共同作用下大直径圆柱绕流现象进行三维数值模拟，对圆柱体局部复杂流动进行了三维湍流计算分析，给出了三维流场、圆柱体表面及其所在局部底床床面应力分布，并在此基础上对圆柱体所在底床的局部冲刷进行了初步分析。
