摘要/Abstract

摘要： 为获得油气混输泵的内部流动规律,研究该泵的混输特性,基于标准k-ε湍流模型和mixtere多相流模型, 对该泵进行气液两相的定常模拟计算,获得其内部压力场、速度场以及气相体积率的分布情况.分析表明,从叶轮进口到叶轮出口气液两相分离情况越来越严重,压力增大,流动紊乱.从导叶进口到导叶出口气泡团逐渐从轮毂处向流道中间移动,压力逐渐减小并出现低压区而导致涡旋现象.

Abstract: In order to reveal internal flow and mixing transport characteristics of an oil-gas pump, the steady gas-liquid two-phase flow simulation, which is based on the standard k-ε turbulence model and the Mixtere multiphase flow model, for the oil-gas pump is carried out by using computer simulation technology. And the distribution of internal pressure field, velocity field as well as gas volume ratio are obtained. Simulation results show that, from the impeller inlet to the impeller outlet, the degree of gas-liquid two-phase separation becomes more and more serious, the relevant pressure increases gradually, and the flow state tends to be turbulent. From the inlet of the guide vane to the exit of the guide vane, the bubble cluster moves gradually from the hub to the middle of the channel, and the relevant pressure decreases gradually also, forming a low pressure zone, which leads to eddy flow phenomenon in the low pressure zone.

Key words: oil-gas multiphase pump, gas-liquid phase, mixing transport characteristics
