Axial Evolution of Helical Modes in Reacting Swirl Flow MIKE
Submitted for the DFD13 Meeting of The American Physical Society Axial Evolution of Helical Modes in Reacting Swirl Flow MIKE AGUILAR, BENJAMIN EMERSON, DAVID NOBLE, TIM LIEUWEN, Georgia Institute of Technology — The swirling jet is a common method of flame stabilization for ground power and aviation combustors. The hydrodynamic stability characteristics of high Reynolds number, reacting, swirl...
متن کاملFlow around a NACA0018 airfoil with a cavity and its dynamical response to acoustic forcing
Trapping of vortices in a cavity has been explored in recent years as a drag reduction measure for thick airfoils. If, however, trapping fails, then oscillation of the cavity flow may couple with elastic vibration modes of the airfoil. To examine this scenario, the effect of small amplitude vertical motion on the oscillation of the shear layer above the cavity is studied by acoustic forcing sim...

متن کاملEffects of cooling flow on the flow structure and acoustic oscillation in a swirl-stabilized combustor. Part II: Acoustic analysis
The effects of cooling flow injection on the flow development and acoustic oscillation in a premixed swirl-stabilized combustor had been numerically investigated using 3D large-eddy simulation. Three different cases, including one with no injection and two with cooling flow injection (5, 20 m s), were simulated. With injection of cooling flow-through slits in the combustor wall, the absolute ve...
