Studies of Detonation Quenching by Water Sprays

摘要: Abstract Methods designed to quench a detonation wave in pipe usually rely on some passive device which often presents an unacceptable impedance the normal flow. One method overcomes this problem is triggered water spray barrier, principles of are examined present study. Experimental data quenching were obtained vertical tube, 76 mm diameter, fitted with various generators. The empirical relations Ranger and Nicholls then used calculate rate at stripped from droplet shock flow field form micromist, thus enabling energy loss wavefront heating vapourising micromist be found. Application Shchelkin criterion mechanism shows that 20% required wavefront. This requirement met distances ranging 0.2 1.0 cell lengths reasonable agreement expected position CJ plane.
