A Short Review and Investigate Study on Performance of Magneto-Hydrodynamic Using High Reynolds Numbers

Abstract

AbstractThis paper presents a short review on working phenomena, existing trends, and investigate study on the performance of Magneto-hydrodynamic (MHD) power generation using high Reynolds numbers. The generators used in the MHD power generation are quite different from traditional electric power generation plants in such a way that they operate at high temperatures. Moreover, the MHD generators did not have any rotational parts, hence, no rotational and friction losses with generating elements. Like conventional generators, the MHD generators also rely on moving a conductor through a magnetic field. These use hot conductive plasma or liquid metals as the moving conductor through a magnetic field to generate the electric power. One of the major drawbacks of the plasma MHD power generation is, it requires a very high operating temperature as the ionized working gases at the temperature rating above 2,000 K. In this work, a low-melting-point gallium alloy is used to investigate the per-performance of the MHD power generator using high Reynolds numbers is analyzed.KeywordsMagneto-hydrodynamic (MHD)Low-melting point gallium alloyHigh reynolds numbersElectric generators
