National Center for Hypersonic Combined Cycle PropulsionClosing Remarks
Research Impact Turbine/Ramjet Transition The Center’s research will lead to deployment of improved and validated methods that will improve the accuracy of future high speed dual-inlet TBCC flowpath calculations, especially the mode transition. An example is the development of immersed boundary techniques for rendering of boundary layer control devices and improved bleed models. Ramjet/Scramjet Transition The Center will provide the scientific community with a unique and comprehensive experimental database for dual-mode scramjet operation, including fuel-air mixing and combustion and the dual-mode transition, using both hydrogen and hydrocarbon fuels. Advanced laser-based flowfield diagnostics will be further developed and applied to provide previously unavailable velocity, species and temperature distributions, and their correlations, to benchmark computational models. Hypervelocity Regime Experimental datasets will be provided by a low-cost impulse facility for CFD validation over a range of enthalpy levels (Mach 5, 7 & 10) in which the flow physics, including nonequilibrium effects, will be quantified. This ground test capability will be made available for future research.
Research Impact (cont) Advanced Modeling Progress toward the development of a 'tip-to-tail' simulation methodology for scramjet components will be made using LES/RANS methods. Advanced closures for turbulence / chemistry interactions will be incorporated into the LES/RANS framework. High fidelity LES/RANS and LES/FMDF models will be developed. These models will be used for numerical simulations of combined cycle systems for conditions which laboratory experiments cannot reproduce. Turbulent mixing and flame holding (extinction/reignition) in high speeds will be studied by LES/FMDF for various combustor geometries and fuel injection strategies, which potentially lead to a better design of fuel injection and flame holding systems. The Center will develop reliable and portable combustion software based on the S-FMDF for use in various production codes. Specifically, the S-FMDF will be incorporated into NASA’s VULCAN code, making it a better combustion solver. A library of DNS data for several fundamental high speed flows will be provided. These data will be invaluable for the development and assessment of advanced CFD models for hypersonic systems. With the detailed analysis of DNS data, a better understanding of shock-turbulence-combustion interactions will be developed. Chemistry modeling Reduced chemical kinetics models and tabulation techniques will be available for realistic, high speed flow calculations by combining them with LES/FMDF. The effect of chemistry on ignition, flame holding and combustor performance will be clarified.
