A series of experiments demonstrating the mitigation of water mist on the over-pressure effects of a TNT detonation have been conducted A series of TNT charges, 0.9 kg 2 lb, 2.2 kg 5 lb and 3.2 kg 7 lb, were detonated both with and without employing a water mist system. The TNT detonations were characterized by five measurements initial blast over-pressure start time, peak, and impulse, as well as quasi-static pressure and start time. The initial blast over-pressure peak and impulse, as well as quasi-static pressure were reduced by the presence of water. These experiments show that the use of water mist to mitigate the over-pressure effects of a high explosive detonation is an extremely promising concept.
