In order to get the flowing law in a liquid metal magnetohydrodynamics(MHD) generator channel, three-dimensional numerical studies on kinetics characteristics of open circuit generators were carried out. A magnetic induction method and a modified K-ε turbulence model based on Fluent were adopted to ensure the calculation precision. A comparative analysis of the velocity and force distribution of near-wall and core was made. The velocity fluctuation was defined and different physical parameters were chosen. The velocity profiles and fluctuations downstream of the effective section were analyzed quantitatively. The results showed that, the velocity fluctuations reached maximum at downstream of the effective section and channel parameters had a significant impact on velocity profiles. The channel width being kept constant, the interaction parameter determined the velocity fluctuation and the velocity fluctuation was proportional to the interaction parameter. As channel width increased, the impact of interaction parameters on velocity fluctuations declined.
