Abstract

Magnetohydrodynamics (MHD) is the study of electrically conducting fluids flowing through applied magnetic fields. MHD can be applied in power generation to produce electricity with no moving mechanical parts. By not using mechanical parts, MHD generators may potentially produce electricity with low capital costs. This form of electrical generation can be paired with advanced nuclear reactors to make the reactors more economically competitive. This paper studies a vertical gravity driven MHD generator system, specifically maximizing the electrical power density output. For an MHD system, there will be a specific magnetic field that, when applied, will produce a maximum power density for the system.
