Abstract

This paper deals with the heat and mass transfer in unsteady flow of Powell-Eyring fluid past an inclined stretching sheet in the presence of radiation, non-uniform heat source/sink and chemical reaction with suction/injection effects. The governing equations are reduced into system of ordinary differential equations using similarity transformation and solved numerically using Runge-Kutta based shooting technique. Results display the influence of governing parameters on the flow, heat and mass transfer, friction factor, local Nusselt and Sherwood numbers. Comparisons are made with the existed studies. Present results have an excellent agreement with the existed studies. Results indicate that an increase in the chemical reaction parameter depreciates the friction factor, heat transfer rate and enhances the mass transfer rate. Dual solutions exist only for certain range of suction/injection parameters.

井环流体通过倾斜拉伸板非定常流动的对偶解

本文研究了鲍威尔-艾环流体在辐射、非均匀热源/吸热汇和化学反应作用下通过倾斜拉伸板的非定常传热传质问题。利用相似变换将控制方程简化为常微分方程组，并利用基于龙格-库塔的射击技术进行数值求解。结果显示了控制参数对流动、传热传质、摩擦系数、局部努塞尔数和舍伍德数的影响。并与已有研究进行了比较。目前的结果与已有的研究结果非常吻合。结果表明，化学反应参数的增大降低了摩擦系数和传热速率，提高了传质速率。对偶解只存在于一定范围内的吸入/喷射参数。

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
