Casson flow ferromagnetic liquid blood flow over stretching region is studied numerically. The domain is influence by radiation and blood flow velocity and thermal slip conditions. Blood acts an impenetrable magneto-dynamic liquid yields governing equations. The conservative governing nonlinear partial differential equations, reduced to ODEs by the help of similarity translation technique. The transport equations were transformed into first order ODEs and the resultant system are solved with help of 4th order R-K scheme. Performing a magnetic dipole with a Casson flow across a stretched region with Brownian motion and Thermophoresis is novelty of the problem. Significant applications of the study in some spheres are metallurgy, extrusion of polymers, production in papers and rubber manufactured sheets. Electronics, analytical instruments, medicine, friction reduction, angular momentum shift, heat transmission, etc. are only few of the many uses for ferromagnetic fluids. As ferromagnetic interaction parameter value improves, the skin-friction, Sherwood and Nusselt numbers depreciates. A comparative study of the present numerical scheme for specific situations reveals a splendid correlation with earlier published work. A change in blood flow velocity magnitude has been noted due to Casson parameter. Increasing change in blood flow temperature noted due to Casson parameter. Skin-friction strengthened and Nusselt number is declined with Casson parameter. The limitation of current work is a non-invasive magnetic blood flow collection system using commercially available magnetic sensors instead of SQUID or electrodes.
对拉伸区域上的卡森流铁磁液体血流进行了数值研究。该区域受辐射、血流速度和热滑移条件的影响。血液作为一种不可渗透的磁动力学液体,产生控制方程。通过相似变换技术,将保守的非线性偏微分控制方程简化为常微分方程。将传输方程转化为一阶常微分方程,并借助四阶龙格 - 库塔格式求解所得系统。研究的新颖之处在于考虑了具有布朗运动和热泳的卡森流穿过拉伸区域时的磁偶极子情况。该研究在冶金、聚合物挤出、纸张生产和橡胶制造板材等领域有重要应用。铁磁流体的用途广泛,电子学、分析仪器、医学、减摩、角动量转移、热传递等只是其中的一部分。随着铁磁相互作用参数值的增加,表面摩擦系数、舍伍德数和努塞尔数减小。对特定情况的当前数值方案的比较研究表明,与早期发表的工作有很好的相关性。由于卡森参数,已注意到血流速度大小的变化。由于卡森参数,注意到血流温度的变化增加。表面摩擦系数增大,努塞尔数随卡森参数减小。当前工作的局限性在于使用市售磁传感器而非超导量子干涉仪或电极的非侵入式磁血流采集系统。
