This research work describes and investigates Williamson nanofluid flow over an exponentially stretching permeable vertical plate with temperature-dependent thermal conductivity and viscosity. The governing non-linear partial differential equations (PDEs) are metamorphosed into coupled non-linear ordinary differential equations (ODEs) by using similarity transformation. The succeeding equations were numerically solved using MATLAB function bvp4c for various values of parameters. For velocity, temperature, concentration, the skin friction coefficient, and the local Nusselt number, data are presented in the form of graphs and tables. It is noted that for increasing values of magnetic parameter M, Williamson parameter λ, and viscosity parameter α, the boundary layer thickness of the velocity profile decreases, while it increases for the temperature profile. The findings of the present work are validated through the published results.
本研究工作描述并研究了威廉姆森纳米流体在具有温度依赖性热导率和粘度的指数拉伸可渗透垂直平板上的流动。通过相似变换将 governing 非线性偏微分方程(PDEs)转化为耦合非线性常微分方程(ODEs)。使用 MATLAB 函数 bvp4c 对各种参数值对后续方程进行了数值求解。对于速度、温度、浓度、表面摩擦系数和局部努塞尔数,数据以图表形式呈现。值得注意的是,随着磁参数 M、威廉姆森参数λ和粘度参数α值的增加,速度剖面的边界层厚度减小,而温度剖面的边界层厚度增加。本工作的结果通过已发表的结果进行了验证。
