Note (General): Ensemble-averaged heat release rates and pressures inside the combustion chambers were measured to better understand the operating characteristics of a twin valveless pulse burner. The combustion flows were also visualized using a high-speed laser schlieren photography. A measurement system of OH chemiluminescence intensity and pressure transducers were used as diagnostic tools. Based on the well-known Rayleigh’s criterion, the effects on the combustion stabilities of varying the equivalence ratio and the mass flux are discussed. Results show that the phase difference between heat release rate and pressure contributes significantly to the pulse combustion stability. In addition, the phase difference does not depend on the mass flux but on the equivalence ratio, indicating that the fuel/air mixing is a determinant factor in the phase relationship. This mixing process was successfully visualized on the schlieren photographs.
