Abstract
MHD power generation is a direct-electricity-generation method involving no mechanical components, such as a turbine. Usually plasma and liquid metal such as mercury are often used in the MHD power generation. However, the power generation using plasma requires high temperature which makes system operation dangerous to environment. Therefore, considering safety, this research aims to use low-melting-point-alloy as a working fluid for the power generation. In this study, the MHD power generation characteristic using the liquid metal was investigated. The results show that the output voltage linearly increases with Rh and a difference of the trend between laminar flow and turbulent flow is hard to see. Moreover, the results show that the characteristics of the output are changed by considering Faraday's law under non-uniform magnetic flux density.
