Velocity Measurements on the Forward Portion of a Cylinder
(The American Society of Mechanical Engineers (ASME), 1990)Velocity measurements in the laminar boundary layer around the forward portion of a circular cylinder are presented. These results are compared to Blasius’ theory for laminar flow around a ... -
Corrosion of Pure Copper in Flowing Seawater Under Cavitating and Noncavitating Flow Conditions
(The American Society of Mechanical Engineers (ASME), 1990)This paper investigates the corrosion of pure copper in flowing seawater under cavitating and non-cavitating flow conditions. Experiments were conducted in a 10 mm × 20 mm working section ... -
A Transient Electromagnetic Flowmeter and Calibration Facility
(The American Society of Mechanical Engineers (ASME), 1990)An electromagnetic flowmeter was developed to measure transient flows at a data rate of 60 Hz. The approach taken was to develop suitable electronics to replace the electronics of a commercially ... -
The Static and Dynamic Characteristics of the Spiral-Grooved Thrust Bearing
(The American Society of Mechanical Engineers (ASME), 1965)A generalized analysis for spiral-grooved thrust bearings is presented. The effects of local radius are considered. For the same grooving geometry and the same inside-to-outside radius ratio, the ... -
Analysis of Transient Pressures in Bubbly, Homogeneous, Gas-Liquid Mixtures
(The American Society of Mechanical Engineers (ASME), 1990)Flow of a gas-liquid mixture in a piping system may be treated as a pseudo-fluid flow if the mixture is homogeneous and the void fraction is small. The governing equations for such flows ... -
The Outflow of Buoyant Releases Including Fire Gases From a Long Corridor Closed at One End
(The American Society of Mechanical Engineers (ASME), 1990)A new simple model is presented for the outflow of buoyant releases, including fire gases, from a long corridor closed at one end. A physical description of the model and application to ... -

A Near-Wall Eddy Viscosity Formula for Turbulent Boundary Layers in Pressure Gradients Suitable for Momentum, Heat, or Mass Transfer
(The American Society of Mechanical Engineers (ASME), 1990)An eddy viscosity formula is proposed for turbulent boundary layers in pressure gradients which is compatible with the slope and intercept of the log law. By having a “y3 ” variation at the ... -
Dynamics of an Elongated Bubble During Collapse
(The American Society of Mechanical Engineers (ASME), 1990)An analytical model is presented to describe the collapse of an elongated bubble, which appears in the core of a cavitating vortex. The flow field is assumed to be irrotational, due to a ... -
The Mean Flow Structure on the Symmetry Plane of a Turbulent Junction Vortex
(The American Society of Mechanical Engineers (ASME), 1990)The mean flow structure on the symmetry plane of a turbulent junction vortex is documented. A two-channel, two-color LDV system allowed nonintrusive measurements of the two velocity components ... -
Viscous Flow Analysis as a Design Tool for Hydraulic Turbine Components
