Abstract

In a one-dimensional formulation, we consider the problem of decay of the discontinuity in a vertical shock tube when a gaseous suspension of water droplets is present in the channel. Such an approach is used for numerical modeling of the conditions of the physical experiment in a shock tube containing a foam screen. We discuss the dynamics of the wave processes involved in passage of the shock wave through the screen, the damping properties of the screen, and the mechanism for attenuation of the shock wave in the foam. We compare the calculated pressure diagram with the measurement results.
