Starting from the principles of the two‐phase‐flow theory the relaxation process of an aerosol with very small polydisperse solid particles behind shock waves has been studied. Different size distributions of the particles in the initial state have been assumed. The overall volume concentration of the particles should be small. Therefore the exchange processes between the phases have a weak influence on the gas phase, only. For the momentum and heat transfer processes molecular effects have been taken into account by simple Knudsen number corrections. Different computations show the time‐dependent deformation of the particle size distribution function during the aerosol relaxation behind shock waves.
