Abstract

This paper deals with unsteady oscillatory flow of viscous incompressible fluid with heat & mass transfer in a horizontal channel partially occupied by porous medium following the Darcy-Brinkman model. The interior territory of the channel consists of two regions; one of them is filled with porous material and second is clear fluid. At the porous medium fluid interface, interfacial coupling conditions for the fluid velocity, temperature and concentration were used to derive the analytical solution. The effects of pertinent physical fluid parameter like porosity, viscosity ratio, density ratio etc. on velocity, temperature and concentration distribution are considered and demonstrated through graphs. Also, the non-dimensional Skin-friction coefficient, Nusselt number and Sherwood number have been calculated and reported in tabular form.
振荡吸力作用下部分被多孔介质占据的水平通道中具有粘性耗散的传热传质
本文采用Darcy-Brinkman模型,研究了部分由多孔介质占据的水平通道中具有传热传质的粘性不可压缩流体的非定常振荡流动。海峡内部由两个区域组成;其中一个是用多孔材料填充的,第二个是透明流体。在多孔介质-流体界面上,利用流体速度、温度和浓度的界面耦合条件导出了解析解。考虑了孔隙度、粘度比、密度比等相关物理流体参数对速度、温度和浓度分布的影响,并通过图形进行了论证。此外,还计算了无量纲皮肤摩擦系数、努塞尔数和舍伍德数,并以表格形式报告。

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.
