Numerical Simulation to Investigate the Effect of Obstacle on Detonation Wave Propagation in a Pulse Detonation Engine Combustor
Pulse detonation technology can be a revolutionary approach for propulsion system since it offers significant fuel efficiency, higher thrust to weight ratio and low cost. Although the design concept of a pulse detonation engine is comparatively simple, but the development and stabilization of sustainable detonation wave front is difficult. Consequently pulse detonation engine technology is stil...
متن کاملToroidal Imploding Detonation Wave Initiator for Pulse Detonation Engines
Imploding toroidal detonation waves were used to initiate detonations in propane–air and ethylene–air mixtures inside of a tube. The imploding wave was generated by an initiator consisting of an array of channels filled with acetylene–oxygen gas and ignited with a single spark. The initiator was designed as a low-drag initiator tube for use with pulse detonation engines. To detonate hydrocarbon...
متن کاملAnalysis for Steady Propagation of a Generic Ram Accelerator / Oblique Detonation Wave Engine Configuration
This study describes a methodology and gives analyses to determine the steady propagation speed of a projectile fired into a gaseous mixture of fuel and oxidizer. For tractability, the steady supersonic flow of an inviscid calorically perfect ideal reacting gas with high activation energy over a symmetric double wedge, unconfined by a cowl, is considered. Propagation speeds are found which give...
متن کاملAirbreathing rotating detonation wave engine cycle analysis
Airbreathing rotating detonation wave engine cycle analysis" a r t i c l e i n f o a b s t r a c t A cycle analysis model for an airbreathing, rotating detonation wave engine (RDE) is presented. The engine consists of a steady inlet system with an isolator which delivers air into an annular combustor. A detonation wave continuously rotates around the combustor with side relief as the flow expan...
متن کاملParallel Algorithm for Detonation Wave Simulation
A parallel algorithm which has sufficient scalability for time accurate solution of a propagating detonation wavefront is developed. The emphasis is placed on reduction of computational time without compromising accuracy. The flow was assumed to be unsteady, inviscid and non-heat-conducting and coupled with finite-rate chemistry. A finite volume formulation was employed to ensure conservation a...
