RISAnalysis of Flow Migration in an Ultra Compact Combustor
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The ultracompact combustor (UCC) has the potential to offer improved thrusttoweight and overall efficiency in a turbojet engine. The thrusttoweight improvement is due to a reduction in engine weight by shortening the ...
A New Spin on Small-Scale Combustor Geometry
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The ultra-compact combustor (UCC) is an innovative combustor system alternative to traditional turbine engine combustors with the potential for engine efficiency improvements with a reduced volume. Historically, the UCC ...
The Effect of Scale and Working Fluid on Sweeping Jet Frequency and Oscillation Angle
Publisher: The American Society of Mechanical Engineers (ASME)

Computational and Experimental Analysis of a Compact Combustor Integrated Into a JetCat P90 RXi
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Ultra compact combustors (UCCs) look to reduce the overall combustor length and weight in modern gas turbine engines. Previously, a UCC achieved self-sustained operation at subidle speeds in a JetCat P90 RXi turbine engine ...
Experimental Analysis of an Ultra-Compact Combustor Powered Turbine Engine
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The innovative ultra-compact combustor (UCC) is an alternative to traditional turbine engine combustors and has been shown to reduce the combustor length and offer potential improvements in combustion efficiency. Prior UCC ...
Swirler Design Parameter Impact on Lean Blowout, Pressure Loss, and Flame Liftoff
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Swirl stabilized combustion is a common technique used in gas turbine engine combustors and is accomplished by introducing swirl into the inlet flow, which enhances mixing and stabilizes the combustion event. Coaxial ...
Sweeping Jets Issuing From the Face of a Backward-Facing Step
Publisher: American Society of Mechanical Engineers (ASME)
Abstract: This study quantified the performance and fluid disbursal capabilities of several fluidic oscillator variations injecting from the face of a backward-facing step. These devices were designed as a replacement for a pair of ...
Internal Geometry and External Wall Effects on Fluidic Oscillator Behavior
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This study quantified the correlation of internal geometry (including Coanda effects) and external walls on oscillation frequency for a fluidic oscillator that was tested for a variety of mass flow rates using CO2 gas. The ...
The Effect of Curved Geometry on Exiting Flow of Fluidic Oscillators
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Traditionally fluidic oscillators are designed to be planar. However, there are applications that may desire the exiting fluid to move in the third dimension. This could allow these oscillators to be more effective in ...
Manufacturing a Ceramic Turbine Rotor for a Compact Jet Engine
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Compact military-grade jet engines offer many potential applications, including use in remotely piloted vehicles, but can be expensive to use for research and development purposes. A study aimed at increasing the power and ...
