National Center for Hypersonic Combined Cycle Propulsion

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.

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.

Student Summary


22 PhD, 2 MS, 4 BS (total of 28 students) currently doing research in the
Center (5 post
-
doctoral fellows not included)


21 of the 28 students (75%) have support from sources other than Center
funds


Center funding for students is greatly leveraged


In the proposal, we said: “Involvement of students (both undergraduate and
graduate) in research is an issue which will be taken very seriously at this
Center. We expect to graduate approximately
thirty five graduate
students
during the course of the Center. We are committed to recruiting
excellent quality students and involving them in high caliber research of the
kind proposed here.”


After 2 years we have engaged 24 graduate students,
well on the way to the proposed 35 over the 5 years
of the grant
