| 摘 要： | 推导了幂律流体在平面渠道进口段内流动的边界层动量和能量积分关系式，采用边界层的动量积分关系式的近似处理方法，对幂律流体平面渠道层流进口段长度及其进口段效应修正系数进行了理论分析与计算，得出了简便实用的计算公式，并对求出的压力降用实验进行了验证，理论分析值与实验值吻合。

| Abstract: | The boundary layer momentum and energy integral equation of power law fluidsin the entrance region of a straight channel was derived.It was theoretically applied to analyse and calculate the effect coefficients of the laminar entrance length and region.Thus,a simple and valuable formula was developed.The tested results of the pressure drop experiment was basically identical with the theoretical ones. |
