Latest Patents

Sun is named on 1 patent: “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 method calculates the volute’s passive rotation velocity and nozzle flow rate using a GMO model and virtual impeller. It then defines a jet mass source using those values as boundary conditions and computes a non-submerged rotating jet flow with multiple nozzles using the VOF method. By simplifying the dishwasher’s multiphysics analysis, the approach conserves computing resources and addresses challenges involving free-surface divergence and estimation of the volute’s passive rotation speed. These steps support accurate prediction of the dishwasher’s overall hydraulic performance.
