A survey of experimental and numerical efforts to model the complex flow field generated by mixing and reaction of fuel injection in supersonic combustor has been made and presented in this paper. Recent interest in developing air-breathing propulsion devices incorporating supersonic combustor has forced many researchers to develop a configuration giving efficient mixing and combustion, also meeting the requirements of flame holding and completion of combustion with sufficient stabilisation in the flow field. - Many experimental and numerical analyses have been reported during the last few decades regarding the characteristics of the complex flow fìeld resulting due to fuel-air mixing and combustion. Computer aided post-processing of the data from measurement or computation could provide realistic picture of process occurring in combustors. Experimental results widely used in CFD code validations are discussed in detail.
