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.
