Research progress on integrated strut-cavity flameholders for afterburners
摘要
Abstract
With increasingly stringent requirements for reduced aerodynamic losses,compactness,and high reliability in advanced aeroengine afterburners,the integration of fuel injection and flameholding structures has become an important design approach.The integrated strut-cavity flameholder combines flow straightening,fuel injection,and flame stabilization within a compact configuration,thereby reducing the number of discrete components and improving flow organization and fuel distribution.This paper reviewed recent advances in the structural development,flow organization,and fuel transport and distribution of integrated strut-cavity flameholders.Particular attention was given to the effects of geometric parameters,spatial arrangement,and inflow conditions on recirculation structures and aerodynamic losses,as well as to the penetration and atomization of liquid jets in crossflow and the spatial fuel distribution under multi-injector conditions.Existing studies indicate that the spatial relationship between the recirculation zones downstream of the strut and within the cavity governs the local flow organization,while inlet residual swirl,cooling jets,and flow-passage boundary conditions further affect the flow field and aerodynamic losses.Fuel transport is jointly influenced by the liquid-to-gas momentum flux ratio,injection angle,local strut geometry,inflow conditions,and injector arrangement.The reported trends vary with geometric configuration,inflow conditions,and injection parameters,and therefore have different ranges of applicability.For practical annular afterburners,further studies should focus on flow organization and fuel distribution under multi-strut,multi-injector,and nonuniform inflow conditions,together with the development of comprehensive evaluation methods accounting for aerodynamic losses,combustion performance,and thermal loads.关键词
