Thermophoretic MHD Flow and Non-linear Radiative Heat Transfer with Convective Boundary Conditions over a Non-linearly Stretching Sheet
摘要:
本文研究了具有非线性热辐射、对流换热和非均匀热源/热汇的磁流体边界层流动,以及热辐射速度和化学反应对流动的影响。采用适当的相似变换,求解所考虑的控制流的偏常微分方程。采用龙格-库塔四五阶Fehlberg方法结合打靶技术求解无量纲控制方程。研究了不同参数如热泳参数、化学反应参数、非均匀热源/热汇参数在速度、温度和浓度分布上的变化,并以图表形式进行了描述。所得结果与以前的结果非常一致。
英文摘要:
The effects of MHD boundary layer flow of non-linear thermal radiation with convective heat transfer and non-uniform heat source/sink in presence of thermophortic velocity and chemical reaction investigated in this study. Suitable similarity transformation are used to solve the partial ordinary differential equation of considered governing flow. Runge-Kutta fourth fifth order Fehlberg method with shooting techniques are used to solved non-dimensional governing equations. The variation of different parameters such as thermophoretic parameter, chemical reaction parameter, non- uniform heat source/sink parameters are studied on velocity, temperature and concentration profiles, and are described by suitable graphs and tables. The obtained results are in very well agreement with previous results.
