RISThe Role of Hydrodynamic Instabilities on Near-Lean Blowout Flame Shapes in a Swirl-Stabilized Spray Combustor
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This study investigates the role of hydrodynamic instabilities on near-lean blowout (LBO) flame shapes in a swirl-stabilized spray combustor. Hydrodynamic instabilities often manifest themselves in swirling flows as a ...
Impact of an Upstream Film Cooling Row on Mitigation of Secondary Combustion in a Fuel Rich Environment
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In advanced gas turbine engines that feature very short combustor sections, an issue of fuelrich gases interacting with the downstream turbine components can exist. Specifically, in combustors with high fueltoair ratios, ...
Parallelized, Automated, and Predictive Imprint Cooling Model for Combustion Systems
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A novel parallelized, automated, and predictive imprint cooling model (PAPRICO) was developed for modeling of combustor liners using Reynolds-averaged Navier–Stokes (RANS). The methodology involves removing the film and ...
Effects of Effusion and Film Cooling Jet Momenta on Combustor Flow Fields
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The effects of effusion and film cooling momenta on combustor flow fields are investigated. Steady, compressible three-dimensional (3D) simulations are performed on a single-swirler combustor using Reynolds-averaged ...
