Detonation wave structure in a vacuum with unitary fuel particles

The structure of steady state detonation in a vacuum with unitary fuel particles is studied. It is shown that the detonation structure lacks a shock wave frozen in the gas, and that the detonation wave zone consists of a contact discontinuity with jump in gas temperature and continuous pressure, a compression relaxation wave with contact discontinuity in the ignition plane and adjacent combustion zone. Parameters of the two-phase flow in the reaction zone are calculated.
