铁磁流体液膜流动的边界层分析在制造过程中有着无穷无尽的实际应用。有鉴于此，我们分析了卡森流体在热辐射和热源/汇不均匀的扩展片上的磁流体动力学膜流。为了研究磁场对流动的影响，我们在不同的流动方向施加了磁场。发现了煤油- fe3o4和煤油- cofe2o4铁磁流体的双溶液。利用相似变换将非线性偏微分方程转化为一组非线性偏微分方程。利用基于R-K策略的射击技术求解转换后的方程。对问题中涉及的物理参数进行了摩擦系数和努塞尔数的数值估计。结果表明，煤油- fe3o4铁磁流体传热速率高于煤油- cofe2o4铁磁流体。
The boundary layer analysis of liquid film flow of ferrofluids has awesome consideration due to its inexhaustible pragmatic applications in manufacturing processes. By keeping this in view, we analyzed the magnetohydrodynamic film flow of Casson fluid past an extending sheet with thermal radiation and non-uniform heat source/sink. To investigate the magnetic field effect on the flow, we applied the magnetic field at various flow directions. Dual solutions are found for kerosene-Fe3O4and kerosene-CoFe2O4ferrofluids. Similarity transformations are used to convert the nonlinear PDE’s as a group of nonlinear ODE’s. R-K strategy based shooting technique is utilized to solve the converted equations. Numerical estimations of the physical parameters involved in the problem are calculated for the friction factor and reduced Nusselt number. It is noticed that the heat transfer rate is high in kerosene-Fe3O4ferrofluid when compared to kerosene-CoFe2O4ferrofluid.
