    摘要:

    采用Mixture多相流模型,、Realizable湍流模型與SIMPLEC算法,，應(yīng)用CFD軟件Fluent對(duì)內(nèi)混式自吸泵自吸過(guò)程的氣液兩相流進(jìn)行了數(shù)值模擬。通過(guò)分析不同含氣率條件下流場(chǎng)的壓力分布、速度分布,、氣相分布，探討了氣液兩相介質(zhì)在泵內(nèi)的運(yùn)動(dòng)情況，一定程度上揭示了內(nèi)混式自吸泵自吸過(guò)程的內(nèi)部流場(chǎng)變化規(guī)律，為自吸泵的設(shè)計(jì)提供更多的參考依據(jù),。

    Abstract:

    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.
