Overpressure development during the combustion of a hydrogen-air mixture partial filling a confined space

摘要

The paper describes the results from experimental studies and theoretical predictions of the final overpressures developed on combustion of a partial volume inside a larger closed vessel. The partial volume is assumed flammable whilst/the remainder of the volume is initially filled with air alone. Particular attention is given to partial volumes of hydrogen-air mixtures. The accuracy of two theoretical models for predicting the final equilibrium pressure throughout the entire closed volume are also assessed.
