Alternate Scramjet Fuel Modeling and Evaluation
Agency / Branch:
DOD / ARMY
Our Phase I program entails examining the addition of micron and nano-sized aluminum particles to hydrogen fuel for use in hypersonic (M>8) scramjet propulsive flowpath concepts being evaluated for long range missile applications. CFD methodology will be used in these studies that has been validated using full scale data sets obtained in the CUBRC LENS shock tunnel facility. Preliminary aluminum burn models for both micron and nano-sized particles will be formulated based on a literature review, and, on present nano particle research of Prof. Yetter and coworkers at Penn State University. These new particle burn models will be incorporated into the CRAFT Tech three-phase Navier-Stokes codes and evaluated via unit problem supersonic combustion studies. An experimental program will be outlined that will serve to improve upon the preliminary burn models developed in the Phase I program. An optional task will evaluate the effects on performance obtainable by use of aluminum particle additives for current axisymmetric and inward turning scramjet concepts now being investigated.
