摘　　要：应用流体力学和非牛顿流体力学理论，利用 Ｐｒａｎｄｔｌ 边界层方程，分析幂率流体绕流恒温壁面时的流动阻力及壁面和流体之间的传热规律，得出绕流时的阻力系数关系式、努谢尔特数与广义雷诺数和普朗特数之间的关系式，并给出了幂率流体绕流水平平板时上述关系式的解．Based on the theory of non Newtonian fluid dynamics as well as Prandtl boundary layer theory, a theoretical analysis for the laminar flow of power law fluid past arbitrary surfaces, which occurs frequently in nature and in engineering practice, is presented. The main problem considered is to predict the drag and the rate of heat transfer from an isothermal surface. The flow past a horizontal flat plate is studied in detail.

关 键 词：非牛顿流体 二维 边界层 流体流动 层流传热
