Latest Patent Applications: Yujian Fang's notable patent application is titled "Overall Hydraulic Performance Prediction Method for Sink-Type Dishwasher." This method involves a comprehensive process that begins with unsteady numerical computation on a dishwasher pump under static conditions to obtain a characteristic pump curve. The process determines the rotation velocity adaptation coefficient (A) and axial velocity coefficient (B). A mapping relationship is established between the composite superposition virtual impeller and the composite impeller. The passive rotation velocity of the volute and the nozzle flow rate are calculated using the GMO model and virtual impeller. A jet mass source is established, utilizing 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 innovative 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.

Conclusion: Yujian Fang's work in hydraulic performance prediction for dishwashers showcases his innovative spirit and dedication to improving appliance technology. His contributions have the potential to enhance the efficiency of dishwashing systems significantly.
