### Abstract

The gas temperature and velocity may increase or decrease in the relaxation zone following a normal shock wave propagating through a dusty gas. In the case of combustible dust gas mixtures the temperature variation is important since it determines the induction time prior to the onset of combustion. The equations governing the flow in the relaxation region behind the shock are solved for the logarithmic derivatives du/u and dT/T for the gas velocity and temperature. Criteria which determine the signs of du and dT in the relaxation zone are derived from these solutions. The signs of du and dT are found to depend mainly on d(CT//p)/D(u//p**2/2), the rate of change of particle thermal energy with respect to particle kinetic energy.
