Numerical investigation of shock interaction with onedimensional transverse array of particles in air
Abstract
In this paper, we present numerical simulations of shock propagation in air over a onedimensional transverse array of particles. Simulations are carried out by varying the particle spacing and shock Mach number. We compute the unsteady inviscid drag coefficient as a function of time and make relevant comparisons to that for a single particle. We find that deviations in the drag coefficient in time from that of a single particle can be correlated to the acousticparticle interaction time. Finally, we investigate and classify the interaction of the bow shocks in front of the transverse array of particles.
