Motion of Plasma Armatures inElectro-Magnetic Launchers Using Lorentz Force

An EM launcher is a new device to rush small-massspecimens up to 300 m/s. The resistance produced by a slippingmetal armature can be avoided using a plasma armature. So,two-dimensional (2-D) plasma models are broadly used as theseare less complex and equally available. The offered model solvesthe complete set of Magneto Hydro Dynamic (MHD): transportequations of mass, momentum, and energy along, with thevector potential form of Maxwell’s equations to account for theelectromagnetic effects. This model is the plasma simulatedmodel of rail gun launcher that has high efficiency and velocity.The Comsol multiphysics software has been used for thispurpose. The simulation procedures have been performed indynamic condition
