Simulation and Analysis of Magnetohydrodynamic Flows Using the DLR TAU Code - Mediums Air and Argon

Kurzfassung

The present study describes the extension of the DLR TAU Code to simulate magnetohydrodynamic effects. The source term formulation for low magnetic Reynolds numbers is implemented. As a first step a perfect gas study in air is conducted and validated against published data. The results are in excellent accordance. The second numerical setup refers to a perfect gas flow in argon over a cone-cylinder. Different values for the constant electrical conductivity in the shock layer are examined. The results are qualitatively in good agreement with published experimental data. The investigation points out the potential of magnetohydrodynamics for aerodynamic control of future flight vehicles, representing a first step in this direction.
