摘要

研究了霍尔电流、辐射热源和一阶粘性流体流动的化学反应、不可压缩流体通过加速等温垂直板的传热传质。利用拉普拉斯逆变换技术求解上升命题。对热格拉什夫数、普朗特尔数、施密特数、质量格拉什夫数等参数的加速度、热读数和吸附进行了研究，给出了数值。研究发现，流体的速度随热量、霍尔电流和格拉什夫值的增大而增大，随辐射的增大而减小。当化学反应增加时，浓度降低。

HALL AND HEAT SOURCE EFFECTS OF FLOW PAST A PARABOLIC ACCELERATED ISOTHERMAL VERTICAL PLATE IN THE PRESENCE OF CHEMICAL REACTION AND RADIATION

We study Hall current, heat source with radiation and chemical reaction of first order viscous fluid flow, incompressible fluid with heat and mass transfer past an accelerated isothermal vertical plate. The inverse Laplace transform technique is used to solve the ascendant mathematical statement. The numerical values are given after our study of the acceleration, thermal reading and adsorption for certain parameters, including thermal Grashof number, Prantdl number, Schmidt number, and mass Grashof number. Based on the study, we found out that the velocity of the fluid increases with increase in heat, Hall current as well as Grashof value and it decreases with increase in radiation. Concentration reduces when chemical reaction increases.

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.
