摘要
将В．В．Голбев方法［５］推广到幂律流体平面渠道间的流动，首先导出幂律流体平面渠道层流边界的能量积分方程通过对能量积分方程的求解，对幂律流体平面渠道的进口段长度，以及进口段效应压力损失和流量修正系数进行了分析和计算，并且讨论了流动指数ｎ对进口段效应诸系数的影响所提供的压力损失系数计算值，在ｎ＝０．７５时和在实验台所做的实验值进行了比较，二者符合得较好。
In this paper,В.В.Голбев method is extended to analyze the laminar boundary layer development flow of power-law fluid in two-dimensional channel.With the boundary layer motion equation,we have first derived the energy integral equation.Then, by solving the energy integral equation,the development of the boundary layer in the entrance region and coefficients of the entrance region effect are analyzed and calculated.Furthermore,the effects of flow-index of power-law fluid and the coefficients of entrance region effect are discussed.In the case of n=0.75,computable value of pressure loss coefficients presented in this paper is basically identical with the experimental value.
