Abstract

Flame propagation In hydrogen-air and hydrogen-oxygen-diluent (nitrogen or carbon dioxide) mixtures has been studied in a horizontal closed tube with a rectangular cross-section. For slow-burning mixtures, flame speeds in the tube, determined using thermocouples, correlate well with the laminar burning velocities.
A one-dimensional, non-adiabatic, flame propagation model has been developed using the experimentally determined, global heat transfer coefficient for the heat loss from the burnt gas to the tube walls. A comparison of the model predictions with the data indicates substantial improvement over adiabatic predictions. The agreement is better for slow flames. The model predictions are sensitive to the burning velocity, thus suggesting a method for obtaining laminar burning velocities by matching pressure predictions with data when turbulence effects are insignificant.
