Gas flow in a system of coaxial cylinders during their partial destruction

The paper presents an investigation of gas flow into a closed volume in the presence of partial and successive destruction of gas-filled cylindrical shells. The region being destroyed is represented as an arbitrarily situated annular slit. The investigation is based on the numerical integration of unsteady gasdynamic equations using the Godunov finite-difference scheme. The effect of gas temperature on pressure variations in the system is analyzed, and data are obtained on gas-flow characteristics as the slit size is varied. The results obtained are of interest in connection with protecting test equipment from destruction during accidents occurring in aircraft and spacecraft flight simulation experiments.
