eddy-viscosity model meaning in Chinese

涡流粘度模型

In chapter 3 , the subgrid eddy - viscosity model for large eddy simulation is applied to calculate the three dimensions unsteady periodic turbulent flow in yantan francis turbine . the pulsating characteristics of some main physical parameters in flow field are found . the calculated axial water thrust of hydraulic turbine agrees with the model - test value
第三章采用大涡模拟亚格子涡粘模型，对岩滩混流式水轮机的流场进行三维非定常湍流分析，得到了流场中各物理量的脉动特性，计算出ms的轴向水推力与模型试验值大小相当；同时论证了对于下机架承重的混流式水轮发电机组可采用其推力轴承负荷作为水电站厂房振动的最大垂直激振荷载。
