摘要

由于MHD-Casson流体在科学技术中的重要作用，已经对通过垂直通道的不稳定MHD-Cassen流体流动进行了几项研究。因此，本文的主要目的是推导Casson流体通过垂直通道的不稳定自由对流MHD流动的精确解。采用合适的无量纲变量，将量纲调节方程转化为无量纲形式，应用拉普拉斯变换（MOLT）方法得到了流动速度和温度的解析表达式。将获得的分析结果与不同的临界参数进行对比，以了解流动现象。将获得的结果与早期的工作进行了比较，但存在一些局限性。结果与现有结果一致。

UNSTABLE MHD CASSON FLUID FLOW PHENOMENA THROUGH VERTICAL CHANNEL

Several studies have been made on unstable MHD Casson fluid flow past a perpendicular channel due to its significant executions in science and technology. For that reason, the major objective of the present article is to derive exact solutions for unstable free convection MHD flow of Casson fluid through a vertical channel. Employing suitable dimensionless variables, dimensional regulatory equations are transmuted into dimensionless form. Method of Laplace transform (MOLT) is applied to get analytical expressions for velocity and temperature of the flow. The acquired analytical results were plotted against different critical parameters to understand the flow phenomena. The obtained results are compared with earlier work with some limitations. The outcomes are in well concurrence with the existing ones.

期刊介绍： The JP Journal of Heat and Mass Transfer publishes peer-reviewed articles in heat and mass transfer which enriches basic ideas in this field and provides applicable tools to its users. Articles both theoretical and experimental in nature covering different aspects in the area of heat and mass transfer such as heat transfer in phase change phenomena, machinery and welding operations, porous media and turbulence are considered. Priority is given to those which employ or generate fundamental techniques useful to promote applications in different disciplines of engineering, electronics, communication systems, environmental sciences and climatology. Because a combination of two or more different technologies in a single device may result into a significant development, the journal extends its scope to include papers with the utility value in electronics and communication system. In this spirit, we are devoting certain number of issues to ‘Mechanical Systems and ICT – Convergence’. Survey articles dealing with certain issues in the context of current developments in heat and mass transfer together with their applications in interdisciplinary topics are also entertained.
