Overpressure Resulting from Combustion of Explosive Gas in an Unconfined Geometry

摘要

In preparation for a series of large-scale spill tests of liquefied gaseous fuels, we were confronted with the problem of designing safe storage facilities for the fuels as part of a proposed spill test facility to be built at the Nevada Test Site. The design had to take into account the potential hazards associated with large quantities of fuel, including the hazard of overpressures which develop during various modes of combustion or explosion. We made a special study of the overpressure question, the results of which are presented here. In this report we summarize all the pertinent information on overpressure that is available in the open literature and present it in a form that can be readily converted into design criteria for the fuel storage facility. Various modes of combustion are reviewed and categorized according to their capability of producing sizable overpressures, and some comments are made on how deviations from the ideal situations considered in analytical studies will affect the results.
