Description
Summary:Rotating Detonation Engine (RDE) is a promising future engine for propulsion either aviation or ground power generation propose. RDE had high-efficiency and high thrust density without compression stages. Nevertheless, RDE is still at an infancy stage that need further study specifically to discover the effect of shape changeable to make it as a versatile engine. Thus, the aim of this research is to study the performance of RDE when using asymmetric vortex shape for combustion chamber. Variable mixing scheme was tested using methane-oxygen reactant. Initiation strategy by using pre-detonator with acetylene-oxygen mixture through 10bar of detonation pressure. RDE with asymmetric vortex shape for combustion chamber was successfully operate with three mode of failure, unstable and continuous detonation wave. The highest thrust generation is 17.7N at equivalence ratio 1.2.
