内容記述 | A three-dimensional Navier-Stokes code with a standard κ-ε two-equation turbulence model in boundary-fitted coordinate system has been developed for a screw-type centrifugal pump. The approach of logarithmic wall function is employed to treat near-wall regions. The interaction between the impeller and the volute casing is remamkable in this pump type. In the present study, to catch up the interaction effect between the two flow fields, we have calculated the flow fields in a volute casing as well as in an impeller simultaneously by exchanging the calculated data between them at every iteration step. Two kinds of data exchange methods as the boundary condition in grids overlapped between impeller and volute casing are discussed. The simulation results show that only the calculation considering the effect of the volute casing can be predicted reasonably well. The measured pressure distributions and visualizes flow patterns are also compared. | |||||
