浑水水力分离清水装置进口及底孔对流场影响的数值模拟
Numerical Simulation on Flow Field Influenced by Inlet and Bottom Outlet in Turbid Water Hydraulic Power Separation Device
摘要
Abstract
Based on the Renormalization Group model,a three-dimensional water-phase flow field in the turbid water hydraulic power separation device was numerically simulated.Then the influence of different inlet dimension,inlet velocity and bottom outlet aperture was investigated based on the simulations.Results showed that the increase of inlet dimension increases the tangential velocity of cylinder region and radial velocity in cone region when discharge is constant,and the flow field of the device is more sensitive to inlet velocity,so when dealing with large discharge should be given priority to increasing inlet dimension.Besides,tangential and axial velocity in cone region will increase with increasing bottom outlet aperture,which helps sediment desilting of device,but leads to the reduction of separated clear water discharge.关键词
