Parameters of Air Cylindrical Shock Waves

摘要

In this paper, we perform a numerical analysis of the parameters of shock waves (SWs) generated during the expansion of cylindrical volumes of compressed methane. A single dimensionless approximation of the overpressure dependence on the distance is obtained using precise numerical solutions. The overpressure values in the SW are estimated for both the near and far zones. Comparison with previously developed similar dependences shows a higher accuracy of the proposed approximation, which allows predicting the consequences of accidents during the rupture of pipelines.
