摘要

在目前的研究中,研究了导电通过指数增长片的埃灵-鲍威尔流体传热的数值解。当薄片在x方向上拉伸时,流动占据了y > 0的区域。MHD、辐射、焦耳热效应和热松弛时间都被用来表示流动情景。紧急问题使用pde表示,然后使用适当的相似性转换将其转换为ode。利用SLM方法对转换问题进行了数值求解。本文的主要目的是比较在存在K变化的情况下用SLM求解速度方程和温度方程的结果,介绍它是求解非线性微分方程的一种精确而合适的方法。创建带有数值结果的表以进行比较。这种对比很重要,因为它显示了连续线性化方法如何精确地求解一组非线性微分方程。然后,根据各种工程参数对生成的解进行了研究和解释。热弛豫周期与热边界层厚度和温度成反比,而Eckert数则相反。随着E - c的增加,通道内的温度升高。

Chemical Reaction and Generalized Heat Flux Model for Powell-Eyring Model with Radiation Effects
In the current research, the numerical solutions for heat transfer in an Eyring–Powell fluid that conducts electricity past an exponentially growing sheet with chemical reactions are examined. As the sheet is stretched in the x direction, the flow occupies the region   y > 0 . MHD, radiation, joule heating effects, and thermal relaxation time are all used to represent the flow scenario. The emergent problem is represented using PDEs, which are then converted to ODEs using appropriate similarity transformations. The converted problem is solved numerically using the SLM method. The main goal of this paper is to compare the results of solving the velocity and temperature equations in the presence of   K changes through SLM, introducing it as a precise and appropriate method for solving nonlinear differential equations. Tables with the numerical results are created for comparison. This contrast is important because it shows how precisely the successive linearization method can resolve a set of nonlinear differential equations. Following that, the generated solution is studied and explained in relation to a variety of engineering parameters. Additionally, the thermal relaxation period is inversely proportional to the thickness of the thermal boundary layer and the temperature, but the Eckert number E c is the opposite. As E c grows, the temperature within the channel increases.
