The purpose of this research is to inspect the mixed convection flow of Eyring-Powell nanofluid over a linearly stretching sheet through a porous medium with Cattaneo–Christov heat and mass flux model in the presence of Hall and ion slip, permeability, and Joule heating effects. Proper similarity transforms yield coupled nonlinear differential systems, which are solved using the spectral relaxation method (SRM). The story audits show that the present research problem has not been studied until this point. Efficiency of numerous parameters on velocity, temperature, and concentration curves is exposed graphically. Likewise, the numerical values of skin friction coefficients, local Nusselt, and Sherwood numbers are computed and tabulated for some physical parameters. It is manifested that fluid velocities, skin friction coefficients, local Nusselt, and Sherwood numbers promote with the larger values of Eyring-Powell fluid parameter . It is also noticed that primary velocity promotes with larger values of mixed convection parameter , Hall parameter and ion slip parameter while the opposite condition is observed for secondary velocity, temperature, and concentration. Furthermore, comparative surveys between the previously distributed writing and the current information are made for explicit cases, which are examined to be in a marvelous understanding.

霍尔和离子滑移对拉伸表面上Eyring-Powell纳米流体混合对流的影响

这项研究的目的是在存在霍尔和离子滑移,渗透率和焦耳热效应的情况下,通过Cattaneo-Christov热和质量通量模型,研究线性延伸片上Eyring-Powell纳米流体在空气中的混合对流。 。适当的相似度变换会产生耦合的非线性微分系统,可使用频谱弛豫方法(SRM)对其进行求解。故事审核显示,到目前为止,尚未研究当前的研究问题。图形显示了速度,温度和浓度曲线上许多参数的效率。同样,针对某些物理参数,计算并列出了皮肤摩擦系数,局部Nusselt和Sherwood数的数值,并制成了表格。结果表明,流体速度,皮肤摩擦系数,局部Nusselt,还应注意的是,随着对流参数霍尔参数的增大,初级速度会提高。 和离子滑移参数 而次级速度,温度和浓度则观察到相反的条件。此外,针对明确的案例进行了先前分发的文字与当前信息之间的比较调查,对它们进行了很好的理解。
