摘要
The paper describes a novel mathematical model to study the physics of fully ionized plasma flow through MPD thrusters otherwise known as magnetoplasmadynamic thrusters.The developed model consists of a set of differential equations obtained by coupling the Navier–Stokes equations with Maxwell’s equations.The model developed was tested for various 1D and 1.5D cases.These simulations have been carried out for a special case of geometries called Tikhonov fitted geometries for alleviating the instability phenomenon commonly known as onset phenomenon in self-field MPD thrusters.The work was also extended to applied field MPD thrusters.A new equation for magnetic field was introduced to incorporate a virtual cathode.All the computations were carried out using a higher order integration scheme.The results obtained were found to be in good agreement with the previous work done on similar models.
