本文研究了任意截面光滑微小通道内不可压缩层流充分发展流动的压降特性。提出了一个紧凑的近似模型，预测各种形状的压降。该模型仅是横截面的几何参数的函数，即，面积周长和极惯性矩所提出的模型进行了比较分析和数值解的几种形状。此外，模型与实验数据的比较，由几个研究人员收集，显示出良好的协议。
Pressure drop of fully developed, laminar, incompressible flow in smooth mini and microchannels of arbitrary cross-section is investigated. A compact approximate model is proposed that predicts the pressure drop for a wide variety of shapes. The model is only a function of geometrical parameters of the cross-section, i.e., area, perimeter, and polar moment of inertia. The proposed model is compared with analytical and numerical solutions for several shapes. Also, the comparison of the model with experimental data, collected by several researchers, shows good agreement.
