The impacts of entropy generation and Hall current on MHD Casson fluid over a stretching surface with velocity slip factor have been numerically analyzed. Numerical work for the governing equations is established by using a shooting method with a fourth-order Runge-Kutta integration scheme. The outcomes show that the entropy generation is enhanced with a magnetic parameter, Reynolds number and group parameter. Further, the reverse behavior is observed with the Hall parameter, Eckert number, Casson parameter and slip factor. Also, it is viewed that Bejan number reduces with a group parameter.
在具有速度滑移因子的拉伸表面上,对熵产生和霍尔电流对磁流体动力学卡森流体的影响进行了数值分析。通过使用带有四阶龙格 - 库塔积分方案的打靶法,建立了控制方程的数值计算方法。结果表明,熵产生随磁参数、雷诺数和群参数的增加而增强。此外,观察到霍尔参数、埃克特数、卡森参数和滑移因子呈现相反的变化趋势。同时,还发现贝扬数随群参数的增加而减小。
