CFD Fuel Injector Design Tool Applicable To High-Pressure Vitiated Augmentor Flow

Liquid fuel injection into heated and vitiated cross flows, at elevated pressures, will be investigated experimentally and through numerical simulations. Experimental efforts will include advanced optical measurements of liquid spray parameters at positions close to the injection site, as well as downstream. Liquid spray modeling will include first-principles, physics-bsaed modeling of liquid breakup and atomization, coupled with a Navier-Stokes flow solver equipped with advanced aerodynamics, droplet tracking, evaporation, and chemical kinetics models. The results will be useful to AFRL, AEDC and the US gas turbine industry in providing a validated simulation code applicable to military turbine augmentors, with the validation performed at operating conditions similare to actual augmentor conditions.
