The impacts of Newtonian heating and a magnetic dipole in a two-dimensional ferrofluid due to a stretchable cylinder are analyzed in this paper. The effects of the homogeneous–heterogeneous reactions and a magnetic dipole are taken into account. Flow is caused by a linear stretching cylinder. Fourier’s law of heat conduction is applied in the evaluation of heat flux. Impacts of emerging parameters on the magneto–thermomechanical coupling are examined numerically. It is seen that the characteristics of magneto–thermomechanical interaction decelerate the movements of fluid particles, thereby strengthening the skin friction coefficient and reducing the heat transfer rate at the surface. Further, it is evident that the curvature parameter has increasing behaviour on the rate of heat transfer in the boundary layer. Comparison with available results for specific cases is found to be in excellent agreement.

铁磁化学反应物种中的热传递

本文分析了牛顿加热和磁偶极子在二维铁磁流体中由于可伸展圆柱体的影响。考虑了均相-非均相反应和磁偶极子的影响。流动是由线性拉伸缸引起的。导热的傅立叶定律适用于热通量的评估。数值分析了新兴参数对电磁热机械耦合的影响。可以看出,磁热机械相互作用的特性使流体颗粒的运动减速,从而增强了皮肤的摩擦系数并降低了表面的传热速率。此外,很明显,曲率参数在边界层中的传热速率上具有增加的行为。
