| description | The eddy current problem in centrifugal pump has been a difficult problem, it is not only difficult to capture the vortex but also cause the calculation problem because of too many numbers of the grid. However, using two dimensional model which can greatly simplify the calculation and save computing resources. In order to study the differences between two dimensional model and three dimensional model simulation results, the vane type centrifugal pump is used as the research object and the numerical simulation method, computational fluid dynamics (CFD), is adopted in this paper. Calculated separately two dimensional (2D) and three dimensional (3D) model for calculation, two dimensional LES turbulence model is chosen and the three-dimensional LES model is adopted. In different working conditions, the two-dimensional and three-dimensional calculation of the vortices, pressure and velocity are compared and analysed, and the similarities and differences between the two dimensional model and three-dimensional model calculation results are obtained. By the above results, it is proved that the two-dimensional model can replace the three-dimensional model in a certain sense. |
