We present results for hypersonic laminar flows around blunt bodies with different strengths of magnetic fields using a 5th order WENO scheme. The air is heated by a shock, but the electrical conductivity of the air is low enough that we use a low magnetic Reynolds number MHD model. We use an ideal gas model so we neglect all high temperature real gas effects, such as dissociation, ionization, changes in specific heats due to rotational and vibrational excitation, etc. The electrical conductivity is put in as a parameter, and we compare results of making it uniform in space versus having it turned on only in regions that are above a certain temperature. Our numerical method is based on the E-CUSP scheme developed by Zha1 et al.
