強磁場作用下の無限垂直多孔質媒体を通る自由対流マイクロポーラー流体流れによる不安定な磁気流体力学熱伝達は、誘導磁場によって数値的に研究されている。この研究は、一定の吸引速度を持つ乱流境界層の冷却問題のために行われる。無条件安定下での有限差分法は、無次元運動量,角運動量,磁気誘導、及びエネルギー方程式を解くために用いられる。流体速度,角速度,誘導磁場,温度分布,磁場と温度分布、さらに定常状態の壁せん断応力だけでなく壁偶応力,電流密度、及び、ヌッセルト数の計算値を、グラフィックで示す。最後に、重要な発見をここに掲載する。

A unsteady MHD heat transfer by free convective micropolar fluid flow through an infinite vertical porous medium under the action of strong magnetic field have been studied numerically with induced magnetic field. This investigation is performed for the turbulent boundary layer cooling problem with constant suction velocity. The unconditionally stable implicit finite difference technique is used to solve the non-dimensional momentum, angular momentum, magnetic induction and energy equations. The computed values of fluid velocity, angular velocity, induced magnetic field and temperature distributions as well as the steady-state wall shear stress, wall couple stress, current density and Nusselt number are shown graphically. Finally, the important findings are listed here.
