摘要

研究了Jeffrey纳米流体稳态MHD换热的非线性热辐射结果,并对边界条件进行了研究。利用基本流体性质和无因次开关参数,借助李群方法将描述该模型的方便的偏微分方程转化为常微分方程系统。该模型的广义流包含了杰弗里参数和非线性热辐射。首先通过李对称群变换将数学模型转化为常微分方程。利用bvp4c MATLAB求解器对改进后的方程进行了数值求解。Jeffrey参数对流体速度起稳定器的作用,而热辐射参数和热源-汇参数对流体流动温度起提高作用。路易斯数、化学反应参数降低了传质流量。同样的皮肤摩擦,Sherwood数和Nusselt数被扩大。

The Upshot of Nonlinear Thermal Emission on a Conducting Jeffrey Nanofluid Flow over a Stretching Sheet: A Lie Group Approach
The upshot of nonlinear thermal radiation of steady state MHD heat transfer of Jeffrey nanofluid together with prescribed boundary conditions of interest was studied. Essential fluid properties, dimensionless switch parameters with the assistance of the Lie group method were used to transform the convenient partial differential equations that describe the present model into a system of ordinary differential equations. The generalized flow of the present model incorporates Jeffrey parameters and nonlinear thermal radiation. The Mathematical model is first renovated into ordinary differential equations by Lie symmetry group alteration. The renovated equations were solved numerically using a bvp4c MATLAB solver. The Jeffrey parameter serves as a stabilizer on the velocity of the fluid while thermal radiation parameter and heat source-sink parameter improves the flow temperature. Lewis number, chemical reaction parameter diminished the mass transfer flow. Equally skin friction, Sherwood number and Nusselt number were expanded.
