Comparison of Linear and Disk AC MHD Power Generation

Abstract:

This paper presents comparative performances of an linear and disk AC MHD power generation with an active power. The configuration of linear and disk consist of the top and bottom stators. the top stator bottom stator winding are connected with a power supply and an electrical load, respectively. The interaction between the metal fluid and traveling magnetic field can be explained by Maxwell’s equations and Ohm’s law based on the method of finite-elements. Power flow and electrical efficiency of an AC MHD power generation have been evaluated by various slip conditions. The optimal operating point of the generator was defined by adjusting slip values. The result confirms that disk AC MHD power generation has high active power more than linear AC MHD power generation at the same slip.
