Computational Modelling of MHD Flow with Applications to Turbines and MPD Propulsion - SFRH/BD/60285/2009

For the numerical simulation of magnetohydrodynamic flow (MHD) two groups of algorithms have been developed. The first group was created to deal with incompressible flow and the second to calculate highly compressible MHD flows. However, nowadays a great number of numerical gas dynamics codes are able to solve the compressible Navier-Stokes equations at all Mach number regimes. Such algorithms are very important for applications in the field of aerospace engineering, where there is often a need to solve complex flow problems involving a wide range of Mach numbers. This is also true for the special case of MHD flow in realistic Magneto-Plasma Dynamics (MPD) thruster geometries. It is known that these devices can produce flows that range from the nearly incompressible to the hypersonic limit.

Still, there is a lack of solvers capable of solving efficiently the compressible MHD equations for the whole range of Mach number regimes. In this project we are developing a numerical method to solve the MHD equations for arbitrary Mach number. This new solver should be used in order to obtain numerical solutions for MPD thrusters geometries. This kind of thruster is currently used for space propulsion and satellite manoeuvring by ESA - European Space Agency.
