- Abstract
- Deflagration experiments are described involving the application of water mists and water sprays to lean hydrogen-air mixtures in a 2m diameter, 2m long test vessel. The fine water mist (no drop size measured) was able to inert a 6% hydrogen in air mixture when the mist volumetric density was at least 0.7 kg/m3. At lower mist densities a deflagration occurred but with a smaller peak pressure than without any mist. Water spray generated from a standard sprinkler (presumably 1/2-inch orifice) operated at 18 gpm (68 1/min) did not produce any discernible effect on the hydrogen deflagrations.
