In this study, laminar magneto-convection flow of a viscous fluid in an inclined enclosure is considered. The temperature gradient is applied on two opposing walls while the other two walls are maintained adiabatic. In order to solve the governing non-linear differential equations, an in-house developed code based on the finite volume method is utilized. The fluid of interest is molten sodium whose thermal and electrical properties such as heat capacity, thermal and electrical conductivity are temperature dependent. Representative results illustrating the effects of the enclosure inclination angle on the contour maps of the streamlines and temperature are reported and discussed. In addition, results for the midsection velocity profile and the average Nusselt number at the hot wall of the enclosure are presented and discussed for various inclination angles and Hartmann numbers. It is observed that for Hartmann number of 600, an increase in the inclination angle leads to the growth of the number of vortices in the enclosure.

倾斜外壳内的磁对流

在这项研究中,考虑了倾斜壳体中粘性流体的层流磁对流。温度梯度施加在两个相对的壁上,而其他两个壁保持绝热。为了求解控制的非线性微分方程,利用了基于有限体积法的内部开发代码。感兴趣的流体是熔融钠,其热和电特性(例如热容,热和电导率)与温度有关。报告并讨论了说明外壳倾角对流线和温度等高线图的影响的代表性结果。此外,给出并讨论了各种倾斜角和哈特曼数时,中部速度曲线的结果以及外壳热壁处的平均努塞尔数。可以看出,对于600的Hartmann数,倾斜角的增加导致外壳中涡旋数的增加。
