Experiments on power generation were conducted under the open-circuit condition to validate theoretical analyses on the power generation characteristics of a co-axial MHD energy conversion device. Considering distribution of externally applied magnetic field and the electromotive force induced by the rotation of the conductive inner cylinder, the results show that the experimental open-circuit voltage was lower than the theoretical one for the wide channel width, whereas the experimental open-circuit voltage was higher than the theoretical one for the narrow channel width. The inclination of the inner cylinder might cause the decrease in effective radial ratio.

同轴磁流体能量转换装置发电特性实验与理论分析

为了验证同轴磁流体能量转换装置发电特性的理论分析，在开路条件下进行了发电实验。考虑外加磁场分布和导电内筒旋转感应电动势，结果表明，对于宽沟道宽度，实验开路电压低于理论值，而实验开路电压由于通道宽度较窄，其值高于理论值。内筒的倾斜可能会导致有效径向比减小。
