Abstract

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MHD能量转换装置发电特性的实验与理论分析
在开路条件下进行了发电实验,以验证同轴MHD能量转换装置发电特性的理论分析。考虑到外加磁场的分布和导电内筒旋转产生的电动势,结果表明,对于宽沟道宽度,实验开路电压低于理论开路电压,而对于窄沟道宽度的实验开路电压高于理论开路电压。内筒的倾斜可能导致有效径向比的减小。
