RISCombustor Stability and Emissions Research Using a Well-Stirred Reactor
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The design and development of low-emissions, lean premixed aero or industrial gas turbine combustors is very challenging because it entails many compromises. To satisfy the projected CO and NOx ...
Weak Extinction Limits of Turbulent Flowing Mixtures
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: An equation has been derived for predicting the weak extinction limits of stabilized flames supplied with turbulent, flowing mixtures of uniform composition. Experiments have been conducted to ...
Weak Extinction Limits of Turbulent Heterogeneous Fuel/Air Mixtures
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Experimental and theoretical studies are made of the factors governing the weak extinction limits of stabilized flames supplied with flowing mixtures of liquid fuel drops and air. The test ...
Studies of Lean Blowout in a Step Swirl Combustor
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The design requirements of a modern gas turbine combustor are increasingly dictated by wide stability limits, short flame length, and uniform mixing. To achieve the best trade-off between these ...
Aerodynamics of Bluff-Body Stabilized Confined Turbulent Premixed Flames
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Detailed information on the influence of geometric and flow parameters on the structure and properties of recirculation zone in confined combusting flows is not available. In this paper, ...
Turbulent Combustion Properties Behind a Confined Conical Stabilizer
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Turbulence properties were investigated in and around the recirculation zone produced by a 45 deg conical flame stabilizer of 25 percent blockage ratio confined in a pipe supplied with a ...
Fluid Dynamics of a Conical Flame Stabilizer
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Turbulence measurements were performed on a 45 deg conical flame stabilizer with a 31 percent blockage ratio, mounted coaxially at the mouth of a circular pipe and supplied with a turbulent ...
Lean Blowout in a Research Combustor at Simulated Low Pressures
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A propane-fueled research combustor has been designed to represent the essential features of primary zones of combustors for aircraft gas turbine engines in an investigation of lean blowouts. ...
JP-8+100: The Development of High-Thermal-Stability Jet Fuel
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Jet fuel requirements have evolved over the years as a balance of the demands placed by advanced aircraft performance (technological need), fuel cost (economic factors), and fuel availability ...
Design and Development of a Research Combustor for Lean Blow-Out Studies
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In a modern aircraft gas turbine combustor, the phenomenon of lean blow-out (LBO) is of major concern. To understand the physical processes involved in LBO, a research combustor was designed ...
