摘要
Abstract
The three-dimensional turbulent flow in an automotive water pump with the impeller balance hole and clearance of wear-rings,which under the external characteristics of the influence,was simulated employing the time-averaged N-S equations, the standard k-εturbulence model by computational fluid dynamics software PumpLinx.The impeller with the balancing hole and clearance in the working conditions of complex flow field was analyzed in each position of the pressure distribution,velocity distri-bution and the impeller cavitation .A comparison with experimental data shows that the experimental results is basically consistent with the experimental observations.Reasonable proposals were put forward to reduce the hydraulic losses of automotive water pump parts.The research results can guide the development and design of the pump as well as the congener products.关键词
