Abstract

: The purpose of this research is to investigate heat and mass transport in a magnetohydrodynamic (MHD) flow of a non-Newtonian viscoelastic fluid on a stretched magnetized surface. The investigations involve modelling the governing partial differential equations with respect to the Cartesian coordinate system. The models are then transformed into a set of coupled ordinary differential equations. Numerical and graphical solutions were obtained using similarity analysis. The effect of the magnetized sheet on the flow behavior; local skin friction, Nusselt, and Sherwood numbers, are presented in tables. It was observed that an enhanced thickening of the thermal boundary layer was due to the induced magnetization of the sheet. This leads to a significant decline in the heat transfer rate. Certain significant discoveries reported in this research discloses that the effect of viscous dissipation and the non-uniform heat transmission have momentous impact in controlling the rate of heat transfer in the boundary layer region. Again, from the outcome of the analysis it is seen that, the effect of appreciating the Soret number or lessening the Dufour number tends to decrease the velocity and temperature profiles while enhancing the concentration dissemination. Magnetizing the surface shows similar effects on the local skin friction, Nusselt number, and Sherwood number. It is concluded that magnetized surfaces significantly influence the rate of cooling and hence the quality of the penultimate product.
非牛顿粘弹性流体在拉伸磁化表面上的MHD流动
本研究的目的是研究非牛顿粘弹性流体在拉伸磁化表面上的磁流体动力学(MHD)流动中的热量和质量输运。研究涉及到在笛卡尔坐标系下建立控制偏微分方程的模型。然后将模型转换为一组耦合的常微分方程。利用相似度分析得到了数值解和图形解。磁化薄片对流动特性的影响;局部皮肤摩擦、努塞尔数和舍伍德数在表格中给出。观察到热边界层的增厚是由于薄片的感应磁化引起的。这导致传热速率显著下降。本研究的一些重要发现表明,粘性耗散和非均匀传热对控制边界层区域的换热速率有重要影响。再次,从分析结果可以看出,增大Soret数或减小Dufour数的效果往往是降低速度和温度分布,同时增强浓度扩散。磁化表面对局部表面摩擦、努塞尔数和舍伍德数有相似的影响。由此得出结论,磁化表面显著影响冷却速度,从而影响次品的质量。
