Abstract

Application, Purpose, and Methodology: The Soret and Dufour effects, which are also referred to as cross-diffusion gradients, are advantageous to the manufacturing of binary alloys, the transmission of groundwater contamination, the extraction of oil, and the separation of gas. These are an example of a gradient, which occurs when substances diffuse over one another. The Dufour effect is responsible for the transfer of heat, whereas the Soret effect is concerned with the movement of materials. Both effects are caused by differences in concentration. Temperature differences are the link between the two effects. The Soret and Dufour statistics, in conjunction with the joule heating process, are utilized by us. Through the use of the convergent series, solutions for temperature, speed, and concentration are ultimately found. Core Findings: The findings of these investigations may give researchers engineering and industrial solutions that are unique and advantageous. The computation that is being done right now demonstrates that the sense of radial velocity diminishes as the Hartman number increases. In addition, the temperature of the fluid drops when there is a greater quantity of Prandtl and Soret than before. Methodology: Using the proper transformations, the numerical solution to the micropolar fluid flow problem over a curved stretched disk entails simplifying the partial differential equation system into an ordinary differential equation. This is done to solve the problem. In the process of converting partial differential equations into ordinary differential equations, similarity transformations are utilized. During the shooting process, we use the Runge-Kutta method to solve coupled equations and obtain numerical solutions. By utilizing the nondimensional radius of curvature, we can determine the nondimensional radius of curvature and report the fluid. Future Work: When compared to flat sheets, curved stretched sheets exhibit differences that result in significant boundary layer strain. This is something that will be worked on in the future. Research in the future might concentrate on further investigating these distinctions and the practical ramifications they have, with the possibility of expanding the scope of the investigation to include a variety of engineering and industrial applications in which these effects play an important role.
曲面上非稳定流的热扩散和扩散热效应
应用、目的和方法:索雷特效应和杜富尔效应也被称为交叉扩散梯度,对二元合金的制造、地下水污染的传输、石油的提取以及气体的分离都非常有利。这些都是梯度的一个例子,当物质相互扩散时就会产生梯度。杜富尔效应负责热量的传递,而索雷特效应则与物质的运动有关。这两种效应都是由浓度差异引起的。温度差是这两种效应之间的联系。我们将索雷特和杜富尔统计量与焦耳加热过程结合起来加以利用。通过使用收敛级数,最终找到温度、速度和浓度的解决方案。核心结论:这些研究结果可为研究人员提供独特而有利的工程和工业解决方案。目前正在进行的计算表明,径向速度感会随着哈特曼数的增加而减弱。此外,当普朗特数和索雷特数比以前更大时,流体的温度也会下降。计算方法使用适当的转换,对弯曲拉伸圆盘上的微极性流体流动问题进行数值求解,需要将偏微分方程系统简化为常微分方程。这样做是为了解决问题。在将偏微分方程转换为常微分方程的过程中,需要利用相似变换。在拍摄过程中,我们使用 Runge-Kutta 方法求解耦合方程并获得数值解。通过利用非维曲率半径,我们可以确定非维曲率半径并报告流体。未来工作:与平面板材相比,弯曲拉伸板材表现出的差异会导致显著的边界层应变。这是今后要研究的问题。未来的研究可能会集中于进一步调查这些区别及其实际影响,并有可能扩大调查范围,以包括这些效应发挥重要作用的各种工程和工业应用。
