THE PROPAGATION OF BLAST WAVES INTO CHAMBERS.
Abstract
The transmission of a blast environment from the exterior of a chamber into the interior is discussed in terms of the aerodynamic mechanisms of the transmission process. The transmission process was divided into these parts: (1) the entrance and expansion of the incident shock wave into and through the chamber; (2) the flow into the chamber developed by the pressure differential across any openings to the exterior and (3) the filling of the chamber by the inflow. A computerized method for predicting the pressure-time profile of the filling process is presented. The methods described were applied to a hypothetical structure and the results are applied to evaluating the methods and comments presented in the discussion. (Author)
