摘要
利用Adomian拆分方法及Mathematica软件的符号计算功能求解了一类胀塑性非牛顿流体边界层方程的近似解,对不同的参数给出了壁摩擦力的近似值及解的分布曲线,数值结果表明所得近似解有相当高的精度。
Approximate solution of a class of boundary layer equations arising in dilatant non-Newtonian fluids is obtained by using Adomian decomposition method and Mathematica symbols calculation software. Approximation of the skin fric-tion and the distribution curve of solutions are given for different parameters. The reliability and efficiency of the approxi-mate solution are verified using numerical solutions.
