Abstract

The equations of magneto fluid dynamics (MFD) are solved for flow within a simplified “energy bypass” scramjet engine. This engine extracts electrical power from the flow through electric and magnetic field interaction just ahead of the combustor section and then returns it to accelerate the flow downstream of it. This problem has been chose to develop an algorithm to solve the MFD equations with strong electric and magnetic field interaction with weakly ionized flows. Although an attempt is made to make the flow as realistically as possible, the main emphasis is on algorithm development. The effects of the Hall current and ion slip are included. Equilibrium gas conditions are assumed. Electron and ion number densities are calculated and used to determine the local electrical conductivity of the gas.
