A terraced 1:240 scale model of the China Lake Naval Weapons Center was constructed to a resolution of one foot vertical increments and placed in the wind tunnel to determine the distances of lower flammability limit (LFL) for 1980, 40 cubic meter spills of Liquefied Natural Gas (LNG) under 4 wind speeds, 5 wind directions, and neutral flow conditions. Measurements of mean velocities, turbulence intensities, velocity spectra and correlations were...
