摘要
把空隙率和气相密度沿管子高度的变化当作连续过程，并以微分单元压力降出发，然后在全管范围内积分，从而导出了气液两相在弹状流情况下的总压力降计算式：△Ｐ＝ ｌｎ（１＋ ）＋Ｚｃ该计算式用于计算弹状流压力降时，简便且准确度高。
Based on the pressure drop of differential element, and Integrated for the whole region , an equation for calculating the total pressure drop of gas-liquid two-phase alug flow was derived as follows:△P= ln(1+ )ZC In doing this, the variations in voidage and gas density along the pipe were considered to be a continuous process. This equation has the advantages of simpler calculation and higher accuracy when it is used to calculate the pressure drop of slug flow.
