Abstract
ABSTRACT
The opening (inlet and outlet for ventilation, doors and windows) in the shelter represents the weakest part in the shelter. Openings for breathing air and cooling have contradictory requirement we can recognize that for protection it would be best to seal the openings, However this would eliminate the function of it and supply of air is needed for breathing thus, solutions had to be found to comply with all the requirements. Blast valves are built in the ventilating openings to stay open for ventilation and to automatically close when pressure increases due to explosion and automatically re-opens when the pressure is released. The paper presents the performance of one type of a blast valve using a numerical approach putting in an open hole in a shelter by using: AUTODYN software to discuss the reduction of the pressure and MATLAB software to argue pressure drop ∕ air flow rate. It also presents the design of the blast valve, spring and how it operates.
