摘要

这项研究工作的目的是考察在存在吸收、粘性耗散和内部热生成的情况下,相对于收缩表面的停滞点流动的特性。由此产生的微分方程系是众所周知的分析求解难题。控制边界层流动的方程采用有限差分法求解。分析包括通过图示和表列值对重要物理量进行检验。我们的研究结果表明,高收缩参数解的存在与所应用的磁场之间存在密切联系。当 Ec 和 α 同时增加时,温度会升高。这些结果还表明热边界层变浅。根据这些发现,温度和热边界层厚度似乎对这些因素的变化很敏感。

Numerical investigation of stagnation point heat transfer with MHD effects using finite difference method: Analysis of thermal absorption and generation
The objective of this research endeavor is to examine the properties of stagnation point flow in the presence of absorption, viscous dissipation, and internal thermal generation with respect to a shrinking surface. The resulting system of differential equations is notoriously challenging to solve analytically. The equations controlling the boundary layer flow were solved using a finite difference method. The analysis includes the examination of important physical quantities through the presentation of plots and tabulated values. Our findings reveal a strong connection between the presence of solutions for high shrinking parameters and the magnetic field that was applied. Temperatures increase when there is an increase in both Ec and α at the same time. These results also suggest a shallowing of the thermal boundary layer. As a result of these findings, it appears that temperature and thermal boundary layer thickness are sensitive to changes in these factors.
