Determination of the Particle Velocity in Detonating Gases by a Magnetohydrodynamic Principle

Abstract
A technique for experimentally determining the hydrodynamic particle velocity in gaseous detonations is described. The technique is based on the magnetohydrodynamic interaction of the ionized reactants and products with an externally applied magnetic field. Particle velocities in 2H2+O2 and 2H2+2O2 detonations were found to be 1.3 mm/μsec and 0.96 mm/μsec, which are in good agreement with those calculated from detonation rate and pressure.
