Abstract
The chapter summarizes the results of a study aimed at internal shock waves interactions with rigid and flexible obstacles in air. The problems of internal shock waves interaction aim at investigation of an interior explosion within a room with limited or no venting. An effective simplified model with lumped parameters based on the Bernoulli equation has been developed for the quasi-stationary phase of the detonation products outflow from the room through the venting openings. A similar effective simplified model with lumped parameters of explosion venting due to separation of the protective cover has been developed. The proposed approach is demonstrated by the simulation of gas outflow from a chamber upon a sudden separation of the cover or upon a rectangular shutter rotation about a fixed line hinge. It was demonstrated that the developed simplified approach is well suited for simulation of the quasi-stationary phase of partially confined explosions and properly describes the pressure relief and gas outflow from the vented room.
