摘要

摘要采用数值方法研究了由非线性拉伸表面与滞止流动引起的导电粘性不可压缩纳米流体流动。布朗运动和热泳对纳米流体的影响也被纳入。利用MATLAB编程，利用四阶龙格-库塔技术求解了二阶非线性边界条件下的控制偏微分方程。用图形表示了辐射参数(Rd)、拉伸参数(n)、布朗运动参数(Nb)、热泳参数(Nt)对温度、速度和传质的影响。图中给出了这些参数对局部努塞尔数(−θ′(0))和局部舍伍德数(−φ′(0))的影响。

A Study of MHD Fluid with Second Order Slip and Thermal Flow Over a Nonlinear Stretching Sheet

Abstract An electrically conducted viscous incompressible nanofluid flow caused by the nonlinear stretching surface with stagnation flow has been investigated numerically. The effect of Brownian motion and thermophoresis on the nanofluid is also incorporated. The governing partial differential equations with nonlinear second order boundary conditions are solved by the fourth order Runge-Kutta technique using MATLAB programming. The effect of the radiation parameter (Rd), stretching parameter (n), Brownian motion parameter (Nb), thermophoresis parameter (Nt) on temperature, velocity and mass transfer are shown graphically. The influence of some of these parameters on the local Nusselt number (− θ′(0)) and local Sherwood number (−ϕ′(0)) are shown by the graphs.
