Numerické modelování proudění v hydrodynamickém čerpadle

Abstract

The diploma thesis is engaged in modelling of flow in hydrodynamic pump, focused on investigation of Y-Q curve stability and efficiency. Firstly the operation of hydrodynamic pumping device and it’s main construction parts are explained and described. The description of numerical modelling and basic equations for chosen turbulent model follows. The main part is devoted to comparison of data obtained by different approaches of rotor modelling and their agreement with physical experiment. Assessment of radial force is described in the end of my thesis. The resulting characteristics are graphically processed and compared.
