摘要：
A numerical model is developed for the thermal fluid flow process in a single stage through flow type centrifugal air moving fan designed for vacuum cleaners. The model predicted data are compared with the experimental results obtained following the industry standards. The agreements between the numerical and experimental results validate the model. Quantitative energy losses in every step along the flow path are reported. Detailed flow structures and pressure distributions are presented. The air-moving performances of the fan under various conditions are explained. Suggestions on design improvement and application of the motor-fan system architecture are given.
