Award Amount: $99,985.00
 

Abstract:

The program focuses on CFD modeling requirements for predicting Multiple Reaction Control Jet (MRCJ) plume flowfields for hypersonic interceptors. Unified k & #949; turbulence model, and varied extensions that provide for scalar fluctutation models (SFM), baroclinic torque effects, realizability constrainst, vorticity/strain non-equilibrium effects, etc. will be systematically evaluated. Complimentary Direct Numerical Simulations (DNS) will provide additional turbulence statistics that are not readily/reliably measured and provide insight into unsteady effects. The DNS data will support enhancements to the CRAFT Tech unified k- & #949; 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 MRCJ. The effort will lead to extended validation of enhanced turbulence modeling tools, increased reliability of aerodynamic drag & heat flux predictions and fills a major gap at the US Army by improving upon jet interaction (JI) simulation capabilities required for design of hypersonic missiles with multiple surface-mounted, fast-reacting jet thrusters.
