    In order to develop of a 1-MW-class radiation-cooled steady-state Self-Field Magnetoplasmadynamic (SF-MPD) thruster head, Kawasaki et al developed a numerical design tool and thermal phenomenon of thruster head were modelized and numerically analyzed. This thruster is called as SF-MPD thruster ISAS model. Get this from a library! Numerical simulation of cylindrical, self-field MPD thrusters with multiple propellants.

The physical regimes created in these thrusters indicate that a variety of numerical methods are required for accurate numerical simulation ranging from continuum formulations to kinetic approaches. Successes of numerical simulation models are demonstrated through specific examples.

    We present nonoverlapping domain decomposition methods for the numerical treatment of compressible viscous plasma flows inside a self—field magnetoplasmadynamic (MPD) accelerator. The magneto—plasma flow is modelled by a system of conservation laws extended by partial differential equations describing the electromagnetic field.   Book Search tips Selecting this option will search all publications across the Scitation platform Selecting this option will search all publications for the Publisher/Society in context. “ Numerical simulation of cylindrical, self-field MPD thrusters with multiple propellants,” in International Electric Propulsion Conference.

A 2-D, two-temperature, single fluid magnetohydrodynamic code which incorporates classical plasma transport coefficients and Hall effects was developed to predict steady-state, self-field magnetoplasmadynamic (MPD) thruster performance.

The governing equations and numerical methods of solution are outlined and discussed. Experimental comparisons are used to. The performance of the magnetoplasmadynamic thruster is predicted using numerical simulation. The thruster mode is self-induced magnetic field with cylindrical electrodes.

The dependence of the thrust level, specific impulse, and the mass flow rate in different total electric currents is investigated. The AUSM+ scheme is utilized to develop a numerical procedure.

The model developed was tested for various 1D and D 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.

An overview is given on a numerical simulation program for applied field magnetoplasmadynamic (AF-MPD) thrusters, which is currently under development at the Institute of Space Systems (IRS). For the numerical simulation of magnetoplasmadynamic (MPD) self‐field thruster flow, the solution of one of the two dynamical Maxwell equations – Faraday's law – is required.

The Maxwell equations and Ohm's law for plasmas can be summarized in one equation for the stream function so that the two‐dimensional, axisymmetric magnetic field can be.

Numerical Simulation of Cylindrical, Self-field MPD Thrusters with Multiple Propellants. By Michael R. Lapointe. Abstract. A two-dimensional, two-temperature, single fluid MHD code was used to predict the performance of cylindrical, self-field magnetoplasmadynamic (MPD) thrusters operated with argon, lithium, and hydrogen propellants.

Anomalous transport effects in an Ar self-field coaxial MPD thruster are presently studied by means of a fully 2D two-fluid numerical code; its calculations are extended to a range of typical operating conditions.
