摘要

在本研究中,研究了具有化学反应性和导热介质的Casson纳米流体通过细长片材的动力学。在用MHD边界层流动实验Cattaneo-Christov理论时,考虑了流体的热载荷。Rosseland近似用于辐射热通量,因为流体在光学上很薄。在流动模型中使用了偏微分方程。这些偏微分方程被转换为常微分方程。采用Runge-kutta方法和发射技术对修改后的方程组进行了数值求解。图表用于描述相关流量参数的影响,而相关工程值的计算则制成表格。当粘非弹性参数(Casson)设置为较高值时,发现速度剖面退化。当不稳定性参数(A)增加时,边界层分布退化。研究结果表明,Casson流体的塑性动态粘度导致速度剖面降低。这篇论文的独特之处在于,它通过Cattaneo Christov理论的实验研究了两种非牛顿流体(Casson Williamson)纳米流体的同时热载荷。据我们所知,没有任何研究探索过文学中的这类研究。

Soret-Dufour Mechanisms on the Thermal Loading of Catteneo-Christov Theories on Magnetohydrodynamic (MHD) Casson Nanofluid Dynamics Over a Stretching Sheet
The dynamics of Casson nanofluid with chemically reactive and thermally conductive medium past an elongated sheet were investigated in this study. The thermal loading of the fluids is considered while experimenting the Cattaneo-Christov theories with MHD boundary layer flow. The Rosseland approximation is used on the radiative heat flux because the fluids are optically thin. Partial differential equations were used in the flow model (PDEs). These PDEs were converted to ordinary differential equations (ODEs). The Runge-kutta method and firing techniques were used to solve the altered equations numerically. Graphs were used to depict the effect of relevant flow parameters, while computations on engineering values of relevance were tabulated. The velocity profile was found to degenerate when the visco-inelastic parameter (Casson) was set to a higher value. The boundary layer distributions degenerate when the unsteadiness parameter (A) is increased. The findings revealed that, the plastic dynamic viscosity of the Casson fluid causes reduction to the velocity profile. This paper is unique because it examined the simultaneous thermal loading of two non-Newtonian fluids (Casson-Williamson) nanofluids with experimentation of Cattaneo-Christov theories. To the very best of our knowledge, no study has explored study of this type in literature.
