摘　　要：利用数值模拟技术对环翼式桥墩周围流场进行数值计算。采用VOF多相流以及标准K-ε紊流模型描述不可压缩粘性流体的三维水动力学特性,计算了不同挡板位置时桥墩周围的流场变化情况。经过计算表明,不同挡板位置对z向流速影响大,当挡板大小与桥墩半径相同,挡板位置在水深1/3处,可以有效防止下潜水流对桥墩底部的冲刷。Using numerical simulation techniques for numerical calculation of the flow field around the ring- wing pier. VOF multiphase flow and the standard K- ε turbulence model are used to describe the three- dimensional incompressible viscous fluid hydrodynamic characteristics,Calculating the different position of the baffle The changes of the flow field around the pier.After the calculation,The different baffle position has a great significance on the Z velocity,when the baffle position at the depth of 1 /3 of the water and the same radius and piers radius,it can effectively prevent the dive water erosion on the bottom of pier.
