Constant Volume Combustion

Hydrogen-air flame stability with different initial pressures is studied in a constant volume combustion cell. The schlieren flame images and the pressure curves are obtained under various initial pressures, equivalence ratios and initial temperatures. The results show that the time of the laminar flame stage is decreasing with the increasing initial pressure. The main reason of the rapid increasing pressure is whether the squish flame appears. The squish flame stage does not occur when the value of the initial pressure is very low. At this time, the varibility of the pressure is very low. The pressure oscillation occurs when the squish flame or the main flame transmits to the under wall surface. Meanwhile, under the different initial conditions, the time of the mixture combustion process stages is often different, and the flame stability is different. At the same time, the flame crtical radius is decreasing when the initial pressure is increasing.
