摘要

. 切线双曲流体是一种非牛顿流体,其本构方程适用于低剪切速率和高剪切速率,主要用于实验室实验和工业。Darcy-Forchheimer流动模型在石油工程等高流量效应普遍存在的领域具有重要意义。在此基础上,本文用焦耳加热的斜板对正切双曲流体的混合对流耗散达西-福希海默流动进行了分析。将流动控制方程转化为非线性微分方程,然后采用射击策略进行求解。通过图表解释了相关的结果。发现流体速度随幂律指数参数和Forchheimer数的增大而减小。发现热浮力参数使流体温度最小化,磁场参数使流体温度最小化。此外,我们注意到Forchheimer数使表面摩擦系数最小,并且随着Eckert数的增大,换热率减小。此外,我们将我们的结果与以前的努塞尔数结果进行了验证,并注意到令人满意的一致性

Heat transfer in Darcy-Forchheimer flow of tangent hyperbolic fluid over an inclined plate with Joule heating
. Tangent hyperbolic fluid is one of the non-Newtonian fluids in which the constitutive equation is valid for low and high shear rates and used mostly in laboratory experiments and industries. The Darcy-Forchheimer flow model is substantial in the fields where the high flow rate effect is the common phenomenon, for instance, in petroleum engineering. With these things in mind, in this article, we analysed the mixed convective dissipative Darcy-Forchheimer flow of tangent hyperbolic fluid by an inclined plate with Joule heating. Flow administering equations were altered as nonlinear ODEs and then resolved using shooting strategy. Pertinent outcomes are explained through graphs. It is discovered that fluid velocity minifies with the rise in the power law index parameter and Forchheimer number. It is detected that the thermal buoyancy parameter minimizes fluid temperature, and the magnetic field parameter ameliorates the same. What’s more, we noticed that Forchheimer number minimizes the skin friction coefficient, and the heat transfer rate is minified with the larger Eckert number. Furthermore, we have verified our results with former results for the Nusselt number and noticed a satisfactory agreement
