Effect of operating parameters on application based performance analysis of PDC: A recent review

Abstract

Pulse detonation engines (PDEs) are advanced propulsion device for next generation of propulsion systems. The PDE combustion processes are filling of fuel-oxidizer, combustion reaction, blow down and purging. In conventional engine deflagration combustion takes places, which propagation speed is less (Ma < 1) rather than detonation combustion process. But detonation combustion process in pulse detonation engine takes place and its flame propagation speed is much higher than sonic (Ma = 1) velocity. So researchers are focusing on PDE combustion process and different propulsion performances enhancement process. Deflagration to detonation transition process takes placed inside the combustor due to effect of different operation conditions and combustor geometry. Further NOx emission mitigation techniques from Pulse detonation combustor (PDC) are big drawback to reduce the pollution. In these regards review studies on recent advances techniques on flame acceleration, NOx formation and propulsion performance have been indicated to increase the performance of the system. Further state of arts of application indicates that pulse detonation engine can be used for green manufacturing process, surface coating and pharmaceutical product manufacturing.
