为更好地对油水进行分离,分析了斜板间油水两相分层流动过程中水层对油层的拖带作用,应用Navier-Stokes方程,建立斜板间油水两相流动速度分布的数学模型.对被拖带油层在不同黏度和厚度条件下的运动速度进行数值模拟,并比较不同油层黏度时斜板间的油水速度分布.计算结果表明:油层黏度增大使油水两相的平均速度差变大,水层对油层的拖带作用降低,而油层厚度的增大可以提高两相之间的拖带作用.
In order to better separate the oil and water, the water layer dragging action on the oil layer during the stratified flow of oil-water two-phase flow was analyzed. The Navier-Stokes equation was used to establish the mathematical model of oil-water two-phase flow velocity distribution between swash plates. The velocity of the towed oil layer under different viscosities and thicknesses was numerically simulated and the oil-water velocity distribution between the inclined plates was compared when the viscosities of the different layers were compared.The calculated results show that the increase of the oil- The effect of water layer on the reservoir dragging decreases, and the increase of reservoir thickness can improve the drag effect between two phases.
