摘要

研究了在存在Soret效应和Dufour效应的情况下，热泳对微极流体通过垂直多孔板的传热传质流动的影响。转换后的守恒方程采用优化的、广泛验证的变分有限元分析进行数值求解。详细考察了重要的无量纲参数——吸力参数()、索雷参数(Sr)、杜弗参数(Du)和热反射参数(τ)对速度、角速度(微旋转)、温度场和浓度场以及剪切应力、努塞尔数和舍伍德数的影响，并将结果以图表和表格的形式显示出来，以了解问题的物理重要性。结果表明，在当前流动问题中，施加壁面流体吸力(V 0 >0)会使速度、微旋转、温度和浓度边界层厚度在η的每一个有限值处都有所降低。

SORET AND DUFOUR EFFECTS ON MHD HEAT AND MASS TRANSFER FLOW OF A MICROPOLAR FLUID WITH THERMOPHORESIS PARTICLE DEPOSITION

The effect of thermophoresis on heat and mass transfer flow of a micropolar fluid in the presence of Soret and Dufour effects past a vertical porous plate have been investigated . The transformed conservation equations are solved numerically using an optimized, extensively validated, variational finite element analysis. The influence of important non-dimensional parameter, Suction parameter ( ), Soret parameter (Sr), Dufour parameter (Du) and thermophoretic parameter (τ) on velocity, angular velocity (micro-rotation), temperature and concentration fields as well as shear stress, Nusselt number and Sherwood number are examined in detail and the results are shown in graphically and in tabular form to know the physical importance of the problem. It is found that the imposition of wall fluid suction (V 0 >0) in this present problem of flow has the effect of depreciating the velocity, micro-rotation, temperature and concentration boundary layer thicknesses at every finite value of η.

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.
