采用有限差分分析来研究平坦通道入口区域的层流磁流体动力流。假设入口处的速度为抛物线（非磁流体动力学完全发展），并在该磁流体动力学入口区域发展为哈特曼速度。速度分布、入口长度和压降在哈特曼数值为 2.5、4、10 和 50 时进行数值计算。计算出的入口长度值与 Maciulaitis 和 Loeffler 的唯一可用结果进行比较。比较显示出显着差异。
A finite difference analysis is employed to investigate the laminar magnetohydrodynamic flow in the entrance region of a flat channel. The velocity is assumed to be parabolic (nonmagnetohydrodynamic fully developed) at the entry and develops to Hartmann velocity in this magnetohydrodynamic entrance region. Velocity profiles, entrance lengths, and pressure drops are numerically computed at values of the Hartmann number of 2.5, 4, 10, and 50. Values of the entrance length computed are compared with the only available results by Maciulaitis and Loeffler. The comparison shows a substantial difference.
