Title: Missile Interceptor Base Flow Simulation
Agency / Branch: DOD / ARMY
Contract: W31P4Q-09-C-0418
Award Amount: $69,988.00


The program focuses on turbulence modeling enhancements for predicting hypersonic interceptor base flows, using existing benchmark data sets. Unified kε and algebraic stress (EASM) turbulence models, shown to adequately simulate fundamental high-speed jet data sets and now being validated with PIV data sets in a NASA Marshall program focused on baseflows, will be used. Complimentary Large Eddy Simulations (LES) will provide additional turbulence statistics that are not readily/reliably measured. The data will support enhancements to the CRAFT Tech unified k-ε turbulence model. The impact of employing a variable turbulent Prandtl and Schmidt number methodology, based on a two-equation scalar variance framework, will be considered for reacting and non-reacting base flows. The effort will lead to extended validation of enhanced turbulence modeling tools, increased reliability of base drag & heat flux predictions and fills a major gap at the US Army by improving upon base region simulation capabilities required for design of hypersonic interceptors. The program will also conduct initial planning for acquisition of "high-quality" baseflow data in the 12"X12" tunnel at the National Center for Physical Acoustics (NCPA), utilizing non-intrusive diagnostics.
