Working Model of Magneto Hydrodynamics System

Magneto Hydrodynamics is a technique through which electrically conductive flue gases are passed through a magnetic field and as a result electricity can be generated. The preliminary requirement for working of MHD is electrically conducting fluids. So we replace the conventional flue gases produced by burning of coal by naturally available salty ocean water. To demonstrate this phenomenon, we conduct an experiment in which salt water is stored in a vessel. It is passed through the MHD generator located above with the help of pump as an experimental set up. Practically, ocean wave energy can be utilised to generate the pump power so that ocean salt water can be made to pass through the MHD generator at the requisite velocity needed. The MHD generator is a vertically held cuboid which contains taper on both ends designed using CAD software Creo Parametric 2.0, PTC. Two permanent magnets are arranged just outside the cuboidal generator’s two opposite faces to produce the necessary magnetic field. As salt water passes through the generator, by MHD principles, electricity is generated and extracted with the help of two copper plates assembled mutually perpendicular to flow and the magnetic field inside the generator. The water then flows back to the stored vessel after passing through the generator. In this way, pollution free and easily available ocean water can be utilized to produce energy with negligible maintenance since it has no rotating part.
