In this investigation, the magnetohydrodynamic pulsatile flow of Casson nanofluid through a vertical channel embedded in porous medium with thermal radiation and heat generation/absorption has been analyzed using Buongiorno model. The influence of viscous and Joules dissipations are taken into account. The governing coupled partial differential equations are reduced to ordinary differential equations using perturbation scheme and then solved numerically by using Runge-Kutta fourth order technique along with shooting method. The impact of various emerging parameters on velocity, temperature, nanoparticles concentration, Nusselt number and Sherwood number distributions are analyzed in detail. Analysis indicates that the temperature distribution increases for a given increase in Brownian motion parameter and thermophoresis parameter, while it decreases with an increase in Hartmann number. Further, the nanoparticles concentration distribution decreases with an increase in the chemical reaction parameter and the Lewis number, while it increases for a given increase in the Brownian motion parameter.

在这项研究中，已使用Buongiorno模型分析了Casson纳米流体通过嵌入在多孔介质中的垂直通道的磁流体动力脉动流，该垂直通道具有热辐射和热量产生/吸收功能。考虑了粘性和焦耳耗散的影响。利用摄动方案将控制耦合的偏微分方程简化为常微分方程，然后使用Runge-Kutta四阶技术和射击方法进行数值求解。详细分析了各种新兴参数对速度，温度，纳米颗粒浓度，努塞尔数和舍伍德数分布的影响。分析表明，对于给定的布朗运动参数和热泳参数增加，温度分布会增加，而随着哈特曼数的增加而减少。此外，纳米颗粒浓度分布随着化学反应参数和路易斯数的增加而减小，而对于给定的布朗运动参数的增加，其纳米颗粒浓度分布增加。
