摘要

本文研究了在垂直多孔板上存在辐射、散热和散热的MHD对流中的传热和传质。垂直于平板的强磁场被施加到流体区域。利用MATLAB内置的bvp4c求解器技术求解控制无量纲方程。利用数学软件对结果进行了计算,并以图形形式显示了进入问题的各种无量纲参数对速度、温度和浓度分布的影响。已经注意到,施加磁场会减慢流体的速度。此外,热辐射效应和普朗特数都完全适用于流体温度。值得注意的是,散热器显著降低了流体温度和流体速度。目前的工作被用于许多现实生活中的应用,例如化学工程、工业过程,一个系统可能包含多个组件,每个组件的浓度在许多不同的情况下从一点到另一点都不同。

Effects of Radiation and Heat Dissipation on MHD Convective Flow in Presence of Heat Sink
The paper examines heat and mass transfer in MHD convective flow across a vertical porous plate in presence of radiation, heat sink, and dissipation of heat. A strong magnetic field is applied perpendicular to the plate and directed into the fluid area. The governing non-dimensional equations are solved using MATLAB built-in bvp4c solver technique. With the use of mathematical software, the findings are computed, and the effect of the various non-dimensional parameters entering into the problem on the velocity, temperature and concentration profiles are displayed in graphical formats. It has been noted that the application of the magnetic field slows down fluid velocity. Additionally, both the thermal radiation effect and the Prandtl number are fully applicable to the fluid temperature. It is significant to notice that the heat sink dramatically reduces fluid temperature and fluid velocity. The current work is utilized in many real life applications, such as chemical engineering, industrial processes, a system may contain multiple components, each of whose concentrations varies from one point to the next in a number of different circumstances.
