High-power-density liquid-metal MHD generator results
Abstract
The experimental results presented herein satisfy one major goal in demonstrating the technical feasibility of two-phase LMMHD (liquid-metal MHD), i.e., operating an MHD generator at power densities equal to or above that anticipated for practical power systems. Power densities of up to 32 MWe/cu m and efficiencies higher than 0.6 at high void fractions were attained for a small 20-kWe generator. Slip ratio, pressure distribution, and voltage profile data are also given. Supporting analytical and experimental studies are summarized. All results are encouraging for the development of large high-efficiency LMMHD generators.
