Ignition, Combustion, Detonation, and Quenching of Reactive Mixtures
Abstract
A one mole hydrogen - one mole bromine mixture has been detonated by shock ignition. To distinguish the shock wave driven into the hydrogen-bromine mixture from a detonation wave which may have formed, the measured wave speeds and pressures were compared with theoretically calculated values. The experimental data were found to be nearly equal to those of the C.J. detonation wave. Calculations of the reaction zone thickness of the wave show that the straight chain reaction mechanism for the hydrogen bromide formation can sustain stable detonation waves. Several series of experiments to quench flames of various gaseous fuel-air mixtures were carried out with three different flame arrestors. The most useful device is a rectangular burner with a large length- to-width ratio. The bunsen type flames were quenched by squeezing them between two movable blocks, which were made from different materials and coated with catalysts and inhibitors. The steady-state condition of various phases of the quenching process, which this device can produce, has made spectroscopic studies possible. These observations revealed that nonequilibrium states are formed during the quenching process.
