Popis:	This work presents an experimental and numerical consideration of the flow developing after a planar shock wave accelerates a cylindrical column of heavy gas seeded with glycol droplets and surrounded by lighter unseeded gas. Special consideration is given to the formation of the gas column, and it is shown that careful modeling of the initial conditions and the tracer behavior is required to accurately match experimental results. Numerical analysis of the instability formation was performed using the Eulerian hydrodynamics code SHAMRC (second-order hydrodynamic automatic mesh refinement code), while the commercial CFD code FLUENT was used to model the formation of the initial conditions used in experiments. Experimental images and numerical results are presented for Mach numbers ranging from 1.2 to 2.1.
