【 摘 要 】

Determination of blast energy suppression characteristics is key to developing new protective techniques ensuring effective blast-suppression capacity, and enabling the formation of a blast-suppression barrier. The Mining Institute of Georgia and CIPPS of the University of Florida have designed a new type of a shock tube for investigating the processes of explosion suppression by a water mist barrier. The shock tube consists of a blast chamber, a tube, a system for dosed supply of fuel and water, sensors, registering equipment, and a process control module. The paper describes the structural and flow characteristics of the shock tube, and the possibilities it may offer for the study of the processes of blast mitigation with water mist.
