Abstract

A top-loading washing machines use a pulsator to raise the pressure and spray water with detergent solution from the top of the clothes in a shower-like pattern, and achieve high washing power by changing the clothes and rubbing the clothes with the pulsator movement. This study used the moving particle simulation to predict the shower flow rate and visualize the flow in the tub by the pulsator. The shower flow rate in the analysis and the relative difference in flow rate due to different pulsator geometries generally agreed with the experimental values. The visualization results of the flow velocity distribution above the pulsator showed that the rotational axial and circumferential velocities varied with time, confirming the characteristics of the flow field depending on the geometry of the pulsators. It was confirmed that the developed pulsator has a flow field that moves clothing in the radial direction of the pulsator.
