Abstract

In this study we analyzed the magnetohydrodynamic forced convective flow of a nanofluid over a slendering stretching sheet in porous medium in presence of thermal radiation and slip effects. We presented dual solutions for no-slip and Navier slip conditions. Using self similarity transformation, the governing partial differential equations are transformed into nonlinear ordinary differential equations and solved numerically using bvp5c Matlab package. The effects of dimensionless governing parameters on velocity and temperature profiles of the flow are discussed with the help of graphs. Numerical computations are carried out and discussed for skin friction coefficient and local Nusselt number. We found an excellent agreement of the present results with the existed results under some special conditions. Results indicate that the dual solutions exist only for certain range of velocity slip parameter. It is also found that the heat transfer performance is high in presence of velocity slip effect.

多孔介质中纳米流体在细长拉伸片上的辐射MHD强迫对流的对偶解

在本研究中，我们分析了热辐射和滑移效应下纳米流体在多孔介质中细长拉伸片上的磁流体动力学强迫对流流动。我们给出了无滑移和纳维耶滑移条件下的双解。利用自相似变换，将控制偏微分方程转化为非线性常微分方程，并利用bvp5c Matlab软件包进行数值求解。利用图形讨论了无量纲控制参数对流动速度和温度分布的影响。对表面摩擦系数和局部努塞尔数进行了数值计算，并进行了讨论。在一些特殊条件下，我们发现本文的结果与已有的结果非常吻合。结果表明，在一定的速度滑移参数范围内存在对偶解。研究还发现，存在速度滑移效应时，传热性能较高。

期刊介绍： TJPRC: Journal of Naval Architecture and Marine Engineering (JNAME) is a peer reviewed journal and it provides a forum for engineers and scientists from a wide range of disciplines to present and discuss various phenomena in the utilization and preservation of ocean environment. Without being limited by the traditional categorization, it is encouraged to present advanced technology development and scientific research, as long as they are aimed for more and better human engagement with ocean environment. Topics include, but not limited to: marine hydrodynamics; structural mechanics; marine propulsion system; design methodology & practice; production technology; system dynamics & control; marine equipment technology; materials science; under-water acoustics; satellite observations; and information technology related to ship and marine systems; ocean energy systems; marine environmental engineering; maritime safety engineering; polar & arctic engineering; coastal & port engineering; aqua-cultural engineering; sub-sea engineering; and specialized water-craft engineering. International Journal of Naval Architecture and Ocean Engineering is published quarterly by the Society of Naval Architects of Korea. In addition to original, full-length, refereed papers, review articles by leading authorities and articulated technical discussions of highly technical interest are also published.
