method for predicting the overall hydraulic performance of a sink-type dishwasher. process begins with unsteady numerical computation on a dishwasher pump under static conditions to obtain a characteristic pump curve. using this curve, rotation velocity adaptation coefficient (a) and axial velocity coefficient (b) are determined. mapping relationship is established between composite superposition virtual impeller and composite impeller. passive rotation velocity of the volute and the nozzle flow rate are calculated using gmo model and virtual impeller. a jet mass source is established, using the nozzle flow rate and the volute's passive rotation velocity as boundary conditions. this leads to a non-submerged rotating jet flow computation with a multi-nozzle setup using the vof method. this approach streamlines the dishwasher's intricate multi-physics, conserves computing resources, and effectively resolves issues related to free surface divergence and estimating the volute's passive rotation speed, leading to an accurate prediction of the dishwasher's overall hydraulic performance.
