Ventilation system pressure transients: small-scale shock tube results
A shock tube is proposed as a means of generating pressure pulses that simulate explosion pressures across ventilation system components. Experimental results using a 76-mm-dia shock tube to evaluate a proposed conceptual design for a 914-mm-dia shock tube are described. Shock tube driver length variation was shown to be an effective method for controlling pressure pulse duration. A double-diaphragm technique proved to be an excellent way to control driver firing pressure using inexpensive diaphragms. No reflected waves from a small high efficiency particulate air filter mounted on the end of the 76-mm-dia shock tube were observed.
