Abstract
There is renewed interest in blast propagation in multi-chamber systems, related to burried bunker systems. In this short report, some idealized test problems are suggested that can be used to evaluate the accuracy of computer code calculations of such problems. The generic problem selected was that of shock wave propagation through a baffle system - either aligned baffles or staggered baffles. The experiments demonstrate the importance of turbulent mixing effects. Energy is stored in the rotational motion of mixing, which blocks or impedes the flow of the system, and leads to a dramatic decay of the transmitted shock strength.
