Abstract:
Results are presented of a numerical calculation of an unsteady two-dimensional axisymmetric wave flow of an inert monodispersed gas suspension from the channel of a shock tube into the surrounding gaseous space under the action of a gas compressed in a high-pressure chamber. The acceleration of dispersed particles inside the tube and in the submerged space behind the diffracting air shock-wave front is analyzed. The effect of the formation of a vortex dispersed ring during dispersion of a particle cloud is discussed. The influence of the governing parameters of the ejected gas suspension layer and the driving gas on the distance of dispersion of a dispersed particle cloud is investigated.
