Effects of Reynolds Number and Tooth Front Angle on Leakage Loss and Heat Transfer Characteristics in a Rotating Labyrinth Seal
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The labyrinth seal is effective in reducing leakage losses at the rotor blade top in the turbine. This study investigates the variation in labyrinth seal performance at different rotational speeds, different Reynolds ...
A Novel Cooling Design and Improvement of a Radial-Inflow Turbine Rotor Blade
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Abstract. With the continuous increase in turbine inlet temperature, traditional uncooled radial-inflow turbines are becoming inadequate for operation in higher-temperature environments. This study investigates both the ...
Heat Transfer Characteristics in a Rotating Pin Finned Duct With Different Protrusion Locations
Publisher: American Society of Mechanical Engineers (ASME)
Abstract: The heat transfer in a pin finned duct is augmented by the protrusion in this study. The realizable k–ε turbulence model coupled with the enhanced wall function is used to obtain the flow structure and heat transfer ...
Infrared Drying Characteristics and Quality Variations of Lily Bulbs Under Blanching Pretreatment
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Infrared drying characteristics and quality variations (color change, hardness, contents of polyphenol and flavonoid) of lily bulbs under blanching pretreatment are investigated. Influences of parameters such as pretreatment ...
Film Cooling in the Cutback for Trailing Edge With Different Incident Angles
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The cutback film cooling was important to decrease the trailing edge temperature and prolong the working life of gas turbines. Many investigations concerning cutback film cooling have already been done. However, only a few ...
