Abstract:

A series of experimental tests were performed in the field to 1 explosively disseminate liquefied natural gas LNG to form an unconfined cloud of measurable size and shape, 2 transfer a detonation wave from a different chemical cloud, but one known to support detonation, into an LNG cloud, and 3 observe and measure the effects of the transferred detonation wave in the unconfined LNG cloud. Based on the results of these feasibility tests, additional experiments are recommended. A two-cloud detonation transfer technique has been used to study the ability of an unconfined LNG cloud to support detonation. In this technique, two clouds are generated and the LNG cloud serves as the test cloud. The second cloud, the driver cloud, is composed of an easily detonable material and is used to generate the detonation wave. For these tests, propylene oxide was utilized as the driver cloud. A detonator in the driver cloud serves as the initiation source. High speed about 4000 framessecond and the medium speed about 400 framessecond cameras and pressure transducers served as diagnostics. The absolute radiometric output from the unconfined LNG cloud can be determined since calibration step wedges were used with films from selected cameras.
