RISEffect of Coolant Crossflow on Film Cooling Effectiveness of Diffusion Slot Hole With and Without Ribs
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The coolant flow condition at the film hole entrance has a notable effect on film cooling effectiveness. The previous studies about internal ribbed crossflow effects are the hole with a circular inlet cross section. In ...
Study on Additive Effect of Film Cooling Effectiveness in Two Rows of Fan-Shaped Holes
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The coolant jet interaction has a great influence on the superposition prediction of multirow film cooling. Although there have been many efforts to reveal the mechanics of additive effect in multirow film cooling, the ...
Response of Marine Boundary Layer Cloud Properties to Aerosol Perturbations Associated with Meteorological Conditions from the 19-Month AMF-Azores Campaign
Publisher: American Meteorological Society
Abstract: his study investigates the response of marine boundary layer (MBL) cloud properties to aerosol loading by accounting for the contributions of large-scale dynamic and thermodynamic conditions and quantifies the first indirect ...
Numerical Investigation on Diffusion Slot Hole With Various Cross-Sectional End Shapes
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The diffusion hole constructed on a slot-type cross section has the potential to obtain high film cooling performance. However, the end shape of the cross section can greatly affect film cooling characteristics. This study ...
Numerical Investigation on Film Cooling Performance of Fusiform Diffusion Holes
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper presents a numerical investigation of the film-cooling performance of a kind of diffusion hole with a fusiform cross section. Relative to the rectangular diffusion hole, the up- and/or downstream wall of the ...
Experimental Investigation of Film Cooling Performance on Blade Endwall With Diffusion Slot Holes and Stator–Rotor Purge Flow
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper focuses on the influences of the discrete-hole shape and layout on the blade endwall film cooling effectiveness. The effect of upstream purge slot injection on the film cooling performance of the discrete hole ...
Systematic Changes in Cloud Radiative Forcing with Aerosol Loading for Deep Clouds in the Tropics
Publisher: American Meteorological Society
Abstract: t has been widely recognized that aerosols can modify cloud properties, but it remains uncertain how much the changes and associated variations in cloud radiative forcing are related to aerosol loading. Using 4 yr of A-Train ...
Geometrical Parameter Effects on Film-Cooling Effectiveness of Rectangular Diffusion Holes
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper presents an experimental investigation of the rectangular diffusion hole. The effects of rectangular aspect ratio and lateral diffusion angle on film-cooling effectiveness were studied at a low-speed flat-plate ...
Film Cooling of Cylindrical Hole With a Downstream Short Crescent Shaped Block
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper presents a method to improve the filmcooling effectiveness of cylindrical holes. A short crescentshaped block is placed at the downstream of a cylindrical cooling hole. The block shape is defined by a number of ...
Effects of Inclination Angle, Orientation Angle, and Hole Length on Film Cooling Effectiveness of Rectangular Diffusion Holes
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Film-cooling effectiveness of rectangular diffusion holes under an inclination angle α = 45 deg, an orientation angle β = 45 deg, and a length-to-diameter ratio of L/D = 8.5 were, respectively, examined in a flat-plate ...
