This work examined combustion modes in a fundamental, axisymmetric, supersonic combustor at flight equivalent Mach numbers ranging from 7.5 to 9.0. Ethylene was injected at a variety of mass flow rates to examine both scram-mode, jet wake stabilized

This paper examines the scram/dual-mode combustion limits of hydrocabon fuels within a Mach 8, scramjet combustor. Flight-equivalent flows were delivered to the axisymmetric, cavity combustor via a reflected shock tunnel. Two scramjet fuels were exam

Surface roughness elements have been used to overcome the large prediction uncertainties of hypersonic boundary layer transition. They provide the ability to force transition at short distances downstream from the tripping element to ensure turbulent

Combustion of ethylene was examined experimentally via free-jet testing of a fundamental, axisymmetric combustor model at conditions representative of Mach 7-8 flight at 50 kPa dynamic pressure. The model consisted of diffusor, constant area isolator

This paper computationally investigates the turbulent heat transfer of sCO flows cooled in large horizontal tubes with diameter of 15.75 mm, 20 mm and 24.36 mm using RANS turbulence models. The numerical models were validated against experimental dat

The dynamics of an optical axisymmetric scramjet, preferred for generic combustion and flameholding studies without the corner boundary-layer effects that distort the freestream and flame propagation in rectangular scramjets, is investigated at Mach
