Film Cooling From Two Rows of Holes Inclined in the Streamwise and Spanwise Directions
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper describes the results of an experimental investigation into the film cooling effectiveness of two rows of holes inclined in the stream and spanwise directions. The effects of hole ...
Velocity and Turbulence Fields in Pipe Entrance Regions in the Presence of Cross Flows
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper reports on an experimental investigation into the velocity and turbulence fields in the entrance region of a circular pipe with cross flow at the entry. The pipe entry is a sharp ...
Flow Transition Phenomena and Heat Transfer Over the Pressure Surfaces of Gas Turbine Blades
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Detailed examination of flow measurements over concave pressure surfaces suggests that interaction of Taylor-Goertler vorticity with mainstream turbulence exerts only limited influence in enhancing ...
The Effects of Free-Stream Turbulence Intensity and Velocity Distribution on Heat Transfer to Curved Surfaces
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper describes a novel method for measuring the local heat-transfer distribution over a curved surface. The effect of free-stream turbulence intensity, ranging in value from 0.016 to 0.092, ...
Evaluation of Surface Infiltration Testing Procedures in Permeable Pavement Systems
Publisher: American Society of Civil Engineers
Abstract: The ASTM method for measuring the infiltration rate of in-place pervious concrete provides limited guidance on how to select test locations and how results should be interpreted to assess surface condition and maintenance ...
Geotechnical Investigation Strategies for Lunar Base
Publisher: American Society of Civil Engineers
Abstract: Geotechnical characterization of potential lunar sites will be a critical part of the planning and design process. The strategies used to conduct a geotechnical investigation will be dictated by the specific needs of the ...
Stability of a Laminar Boundary Layer Flowing Along a Concave Surface
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Görtler instability for incompressible laminar boundary-layer flows over constant curvature concave surfaces is considered. The full linearized disturbance equations are solved by the Galerkin ...
Darryl E. Metzger Memorial Session Paper: The Streamwise Development of Görtler Vortices in a Favorable Pressure Gradient
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Measurements are presented of the streamwise velocity variation within a laminar boundary layer on a concave surface of 4 m radius of curvature for which the free-stream velocity gradient factor ...
Assessment of Clogging Dynamics in Permeable Pavement Systems with Time Domain Reflectometers
Publisher: American Society of Civil Engineers
Abstract: Infiltration is a primary functional mechanism in green infrastructure storm water controls. This study used time domain reflectometers (TDRs) to measure spatial infiltration and assess clogging dynamics of permeable ...
Pressure Oscillations in a Water-Cooled Nuclear Reactor Induced by Water-Hammer Waves
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Shutdown of the Babcock & Wilcox nuclear reactor water coolant pumps will cause check valves to close which will induce the generation of water hammer in the system. The magnitude, frequency, ...
