Abstract

In this study, the Spectral Relaxation Method (SRM) is used to solve the coupled highly nonlinear system of partial differential equations due to an unsteady flow over a stretching surface in an incompressible rotating viscous fluid in presence of binary chemical reaction and Arrhenius activation energy. The velocity, temperature and concentration distributions as well as the skin-friction, heat and mass transfer coefficients have been obtained and discussed for various physical parametric values. The numerical results obtained by (SRM) are then presented graphically and discussed to highlight the physical implications of the simulations.

摘要

在本研究中，采用谱松弛方法（SRM）来求解由于不可压缩旋转粘性流体中二元化学反应和阿累尼乌斯活化能存在时，拉伸表面上的非定常流动所导致的耦合高度非线性偏微分方程组。针对各种物理参数值，已获得并讨论了速度、温度和浓度分布以及表面摩擦、传热和传质系数。然后以图形方式展示并讨论了由（SRM）获得的数值结果，以突出模拟的物理意义。
