The invention discloses a LMMHD power generation system and working method based on the flow pattern active regulation mechanism. After the liquid metal is raised to a certain temperature by the heat source, the liquid metal and the low boiling point working medium are mixed with the mixer, so that the low boiling point working medium is vaporized to promote the liquid metal flow, and then the two phases of the mixed fluid are further mixed through the flow pattern regulation device. The fully mixed two-phase fluid then flows through the power channel and is eventually separated in a separator. By optimizing the design of the MHD power generation system, the invention can effectively solve the problem that the mixing fluid of the mixer is not uniform and the conductivity is poor, and provide the two-phase fluid with good mixing effect for the power generation channel, thus greatly improving the power generation performance of the whole system. In addition, the invention can be adapted to a variety of heat sources, has the advantages of rapid adjustment response, simple and compact adjustment device, etc., and can effectively improve the power generation performance of the MHD power generation system.
