In present study, we analyze the numerical and theoretical studies of the Darcy–Forchheimer MHD Williamson incompressible fluid flow near a nonlinear stretched surface in the presence chemical reactive species. Darcy–Forchheimer effect and viscous dispassion are considered under the entropy generation. Entropy generation analysis has designated great interest in applied engineering procedure to improve the mathematical and theoretical elevation problem. To approximate the entropy generation rate, the ordinary differential equations are solved numerically by utilizing fifth-order Runge–Kutta integration scheme with shooting method. Next using the production results, the entropy results are examined by utilizing numerical and theoretical approaches. The numerical date acquired for several mechanisms are shown through figures and tables. The physical effects of the several interesting parameters on the base flow, heat and mass transfer are discussed through graphs and tables.

具有热扩散的威廉姆森流体流动的熵产生最小化和化学响应

在本研究中,我们分析了存在化学反应性物种的非线性拉伸表面附近的达西-福希海默MHD威廉姆森不可压缩流体流动的数值和理论研究。在熵的产生下,考虑了达西-福希海默效应和粘性弥散。熵产生分析在应用工程程序中引起了极大的兴趣,以改善数学和理论上的高程问题。为了近似熵的产生速率,利用带射击方法的五阶Runge-Kutta积分方案对常微分方程进行数值求解。接下来使用生产结果,通过数值和理论方法检查熵结果。通过图表显示几种机制获得的数字日期。
