==OVERALL HYDRAULIC PERFORMANCE PREDICTION METHOD FOR SINK-TYPE DISHWASHER - A simplified explanation of the abstract==


This abstract first appeared for US patent application 20240281568 titled 'OVERALL HYDRAULIC PERFORMANCE PREDICTION METHOD FOR SINK-TYPE DISHWASHER

The abstract describes a method for predicting the overall hydraulic performance of a sink-type dishwasher using numerical computations and mapping relationships between components.

* Unsteady numerical computation is used on a dishwasher pump under static conditions to obtain a characteristic pump curve.
* Rotation velocity adaptation coefficient (a) and axial velocity coefficient (b) are determined based on the pump curve.
* A 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 the GMO model and virtual impeller.
* A jet mass source is established to compute non-submerged rotating jet flow with a multi-nozzle setup using the VOF method.
