Validation and numerical testing of turbine augmentors combustion computational modeling

"This proposed Phase II modeling effort is designed to improve the accuracy of numerical predictions of military gas turbine augmentors through a coordinated program of physics-based modeling improvements within the selected, state-of-the-art ComputationalFluid Dynamics (CFD) flow solver (named FP-Augmentor), and a concurrent test program to provide essential validation data for key models. The major modeling tasks will include implementation of efficient chemistry models for jet fuels, validations, andapplications to predict flow in high-performance gas turbine augmentors, using geometry and flow information provided by AEDC and turbine manufacturer organizations. The major experimental task includes the testing of a single spray bar, representative ofconfigurations currently in use in industry, and the detailed measurement of cold flow spray droplet characteristics as measured using advanced optical instruments for local velocity and droplet diameter data. Limited combustion experiments will beconducted with the spray bar, in the year two of this study."
