RISDevelopment and Applications of a Coupled Particle Deposition—Dynamic Mesh Morphing Approach for the Numerical Simulation of Gas Turbine Flows
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The presence and accretion of airborne particulates, including ash, sand, dust, and other compounds, in gas turbine engines can adversely affect performance and life of components. Engine experience and experimental work ...
Experimental Deposition of NaCl Particles From Turbulent Flows at Gas Turbine Temperatures
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The ingestion and deposition of solid particulates within gas turbine engines has become a very significant concern for both designers and operators in recent times. Frequently aircraft are operated in environments where ...
Reduction in Flow Parameter Resulting From Volcanic Ash Deposition in Engine Representative Cooling Passages
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Internal cooling passages of turbine blades have long been at risk to blockage through the deposition of sand and dust during fleet service life. The ingestion of high volumes of volcanic ash (VA) therefore poses a real ...
Heat Transfer in the Core Compressor Under Ice Crystal Icing Conditions
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: It has been recognized in recent years that high altitude atmospheric ice crystals pose a threat to aircraft engines. Instances of damage, surge, and shutdown have been recorded at altitudes significantly greater than those ...
Particle Bounce Stick Behavior in the Rotating Frame of Reference
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Particle deposition is a major damage mechanism for gas turbine components, especially in the secondary air system. Predicting the transport and deposition of ingested atmospheric contaminants is of great interest in ...
