摘要

给出了垂直微孔通道中由于不对称加热而形成的稳定磁完全自然对流的精确解。控制动量和能量方程以无因次形式提出，并采用待定系数法进行解析求解。利用折线图和表格讨论了霍尔电流和吸注参数对初级和次级速度、体积流量和表面摩擦力的影响。观察到，在一次流和二次流方向上，注射加速了流动，而吸力减慢了流动。

Fully developed magnetohydrodynamics natural convection flow in a vertical micro-porous-channel with Hall effects

An exact solution is presented for the steady hydromagnetic fully developed natural convection flow in a vertical microporous channel due to asymmetric heating. The governing momentum and energy equations are presented in dimensionless form and solved analytically using the method of undetermined coefficient. The effects of Hall current and suction/injection parameters on the primary and secondary velocity, volume flow rates, and skin frictions are discussed with the help of line graphs and tables. It is observed that injection accelerates the flow, whereas suction retards the flow in both the primary and secondary flow directions.
