Li is associated with 1 patent, titled “Overall Hydraulic Performance Prediction Method for Sink-Type Dishwasher.” The method begins with unsteady numerical computation of a dishwasher pump under static conditions to obtain its characteristic curve. It uses that curve to determine a rotation velocity adaptation coefficient (A) and an axial velocity coefficient (B), then establishes a mapping between a composite superposition virtual impeller and a composite impeller.

The approach calculates the volute’s passive rotation velocity and nozzle flow rate using a GMO model and a virtual impeller. These values serve as boundary conditions for a jet mass source, enabling computation of a non-submerged rotating jet flow with multiple nozzles using the VOF method. By simplifying the dishwasher’s multiphysics analysis, the method conserves computing resources and addresses challenges involving free-surface divergence and estimation of the volute’s passive rotation speed. Its aim is to support accurate prediction of overall hydraulic performance.
