Off-Design Performance Characteristics of Supercavitating Hydrofoils in Cascade
(The American Society of Mechanical Engineers (ASME), 1970)The performance characteristics of supercavitating flapped foils in cascade, (such as the lift coefficient, the drag-lift ratio, and the limiting inlet flow speed) are calculated, for various ... -
A Multiple Critical Flow Venturi Airflow Metering System for Gas Turbine Engines
(The American Society of Mechanical Engineers (ASME), 1970)An air metering system has been constructed using an array of critical flow venturis. By plugging individual venturis, the total metering area is varied to provide an airflow range from 25 ... -
Wear of Small Orifices by Streaming Current Driven Corrosion
(The American Society of Mechanical Engineers (ASME), 1970)Wear on the upstream side of small metal orifices subject to large pressure drops (3000 psi) in phosphate ester base hydraulic fluids has been found to be the result of an electrochemical ... -
The Gaseous Squeeze-Film at Moderately Large Squeeze Numbers
(The American Society of Mechanical Engineers (ASME), 1970)The asymptotic analysis of the gaseous squeeze-film bearing has been extended to obtain 0 {σ−1/2 } effects in accordance with the isothermal gas lubrication theory and the method of singular ... -
A Statistical Approach to the Prediction of Discharge Coefficients for Concentric Orifice Plates
(The American Society of Mechanical Engineers (ASME), 1970)New equations are developed which predict the coefficients of discharge for concentric orifice plates as functions of line size, diameter ratio, and Reynolds number. These are developed using ... -
Precise Measurement of Differential Pressure When Calibrating a Head Class Flow Meter
(The American Society of Mechanical Engineers (ASME), 1970)When flow calibrating a head class meter to establish its discharge coefficient, measurement of the fluctuating differential pressure has caused the largest uncertainty. With conventional techniques, ... -
Laminar Separation, Reattachment, and Transition of the Flow Over a Downstream-Facing Step
(The American Society of Mechanical Engineers (ASME), 1970)Results of an experimental investigation of the laminar flow of air over a downstream-facing step are presented. The experiments include visual observations of smoke filaments (in the viscous ... -
A Field Method of Determining Gas Turbine Meter Performance
(The American Society of Mechanical Engineers (ASME), 1970)The need for a simple and inexpensive method for field checking gas turbine meters exists. One such method called the “spin test” is described in this paper. The relationship between the ... -
Turbine Flowmeter Performance Model
(The American Society of Mechanical Engineers (ASME), 1970)A theoretical model of a turbine meter operating in the high Reynolds number regime has been formulated to study the effects of retarding torques, inlet velocity profile, blade interference ... -
Bubble Formation Due to a Submerged Capillary Tube in Quiescent and Coflowing Streams
(The American Society of Mechanical Engineers (ASME), 1970)The case of bubble formation in both quiescent and moving streams due to the injection of a constant gas flow through a small tube is considered. Relationships predicting the expected size ... -
On the Thermodynamics of Nucleation in Weak Gas-Liquid Solutions
(The American Society of Mechanical Engineers (ASME), 1970)Gas-vapor nucleation in liquid solutions is considered. It is shown that for nucleation to occur in a multicomponent solution a nucleus must be created of at least a certain radius. Consideration ... -
Effects of Heterogeneous Nucleation of Water Vapor in Nozzles
(The American Society of Mechanical Engineers (ASME), 1970)Condensation initiated by heterogeneous nucleation, which is surface dependent, is examined experimentally for the case of rapid nozzle expansions of water vapor. In contrast to previous de Laval ... -
Nuclei and Cavitation
(The American Society of Mechanical Engineers (ASME), 1970)This paper is a review of existing knowledge on cavitation nuclei. The lack of significant tensions in ordinary liquids is due to so-called weak spots or cavitation nuclei. The various forms ... -
Behavior of Liquid Sodium in a Sinusoidal Pressure Field
(The American Society of Mechanical Engineers (ASME), 1970)Utilizing an ultrasonic vibratory cavitation facility, the onset of cavitation was observed in liquid sodium for different liquid sodium temperatures and at various sinusoidal pressure field ... -
