(一)前言 油、气、水混合物多相管流的压降计算方法,按照对于流动型态处理的不同,大致可以分为两类: 一、将多相管流的各种流动型态反映于阻力系数的规律之中,而不单独地考虑流动型态。 二、先确定多相管流在不同位置的流动型态,然后按照不同的规律计算压降。 关于第一类方法,我们的研究结果以前已经报导。本文所介绍的,属于第二类
(A) Preface The pressure drop calculation method of multiphase flow in oil, gas and water mixture can be divided into two types according to the different flow pattern processing. First, the various flow patterns of multiphase flow are reflected In the law of the drag coefficient, without considering the flow pattern separately. Second, first determine the flow pattern of multiphase flow in different locations, and then calculate the pressure drop according to different laws. Regarding the first type of method, our findings have been reported previously. This article describes, belong to the second category
