RISA Study of Thunderstorm Formation Along Dry Lines
Publisher: American Meteorological Society
Abstract: A study designed to point out the effect of the frequently sharp CT-MT boundary, herein called the ?dry line,? on thunderstorm development was undertaken using synoptic surface charts, upper air soundings, 500-mb charts, ...
Plume Model for Buoyancy-Induced Flow and Heat Transfer in Closed Rotating Cavities
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The radial clearance between the rotating blades and stationary casing of a gas-turbine compressor depends on the radial growth of the rotating discs to which the blades are attached, and this growth depends on the ...
Effect of Radiation on Heat Transfer Inside Aeroengine Compressor Rotors
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The blade clearance in aero-engine compressors is mainly controlled by the radial growth of the compressor discs, to which the blades are attached. This growth depends on the radial distribution of the disc temperature, ...
Theoretical Model of Buoyancy Induced Flow in Rotating Cavities
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The Ekmanlayer equations, which have previously been solved for isothermal source–sink flow in a rotating cavity, are derived for buoyancyinduced flow. Although the flow in the inviscid core is threedimensional and ...
Effect of Buoyancy-Induced Rotating Flow on Temperatures of Compressor Disks
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Calculation of the clearances between the blades and casing of the high-pressure-compressor rotors in aeroengines involves calculating the radial growth of the corotating compressor disks. This requires the calculation of ...
Theoretical Model of Buoyancy-Induced Heat Transfer in Closed Compressor Rotors
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The cavities between the rotating compressor disks in aero-engines are open, and there is an axial throughflow of cooling air in the annular space between the center of the disks and the central rotating compressor shaft. ...
Correlation Among Shear Rate Measures in Vascular Flows
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A variety of shear rate measures have been calculated from hemodynamic data obtained by laser Doppler anemometry in flow-through casts of human aortic bifurcations. Included are measures sensitive ...
Use of Fin Equation to Calculate Nusselt Numbers for Rotating Disks
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Conduction in thin disks can be modeled using the fin equation, and there are analytical solutions of this equation for a circular disk with a constant heattransfer coefficient. However, convection (particularly free ...
Review of Buoyancy Induced Flow in Rotating Cavities
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Buoyancyinduced flow occurs in the cavity between two corotating compressor disks when the temperature of the disks and shroud is higher than that of the air in the cavity. Coriolis forces in the rotating fluid create ...
