Abstract : Work during the three-year project timeframe has been focused on 1-1) completing the construction of an arc-heated hypersonic combustion test rig(ACT-1) at the University of Notre Dame (ND), 1-2) characterizing turbulent flame dynamics under various supersonic and hypersonic freestream conditions (Mach 4.5, 6 and 9), and 1-3) developing tools for quantitative turbulent flow measurement methods (in collaboration with Dr. Campbell D. Carter of AFRL) including a new laser diagnostics technique for simultaneous fuel concentration and gas density measurements in supersonic combustors, and 1-4) controlling/quantifying freestream turbulence and evaluating its influences on the turbulent flame dynamics in the high-Reynolds scramjet flows
