摘  要:
采用Mixture多相流模型、Realizable湍流模型与SIMPLEC算法,应用CFD软件Fluent对内混式自吸泵自吸过程的气液两相流进行了数值模拟。通过分析不同含气率条件下流场的压力分布、速度分布、气相分布,探讨了气液两相介质在泵内的运动情况,一定程度上揭示了内混式自吸泵自吸过程的内部流场变化规律,为自吸泵的设计提供更多的参考依据。

摘  要:
3-D simulation was performed for the gas-liquid two-phase turbulent flow in self-priming pump by using Fluent software with Mixture model,SIMPLEC algorithm and Realizable turbulence model.The gas-liquid two-phase flow in self-priming pump was investigated in the pressure in the pump,the velocity in the pump,the distribution of gas and liquid phase in the pump.To some extent,the results reveal the self-suction process of the two-phase flow in self-priming pump,and provide references for self-priming pump design.
