摘　　要：　本文采用数值模拟的方法研究油水混合物在直管和螺旋管中的流动状况。计算采用Euler Euler法和Euler模型:支配油水分离两相流动的基本方程包括连续方程和动量方程,湍流模型采用多相流中混合型k ε模式,基本方程的离散和求解采用SIMPLE算法。利用Fluent软件,以直管和螺旋管为例进行了计算,获得了初步计算结果。计算表明,本文所用方法可以较好地模拟直管中油水在重力作用下的分离,以及螺旋分离器中油水在重力和离心力共同作用下的分离现象。并可为实验研究提供参考。Separation of oil-water mixture flow in both straight and helical pipes is studied numerically, in which the Euler-Euler method and Euler model are adopted. The basic control equations for the oil-water two-phase flow separation consist of the continuity equations and the momentum equations. The k-ε mode is used as the turbulence model and the SIMPLE algorithm is applied for the discretization and solution of the basic control equations. Some numerical results for both straight and helical pipes are obtained with the commercial software Fluent. The results indicate that the methods proposed in this paper may simulate the oil-water separation in the straight pipe by gravitational force and that in the helical pipe by both gravitational and centrifugal force, and the results may afford reference to the experiment.
