Cross-Ventilation of Underground Railway Tunnels
(The American Society of Mechanical Engineers (ASME), 1979)The aerodynamic merits and demerits of cross-ventilating adjacent tunnels in underground rapid transit systems are discussed. Three types of cross-ventilation are considered, namely (a) numerous ... -

Observation of Flow in a Ring Inlet Chamber
(The American Society of Mechanical Engineers (ASME), 1979)We present the results of visualization and quantitative measurements of the flow in a simplified model ring chamber of the type used in axial-flow turbomachinery (see Fig. 1) to distribute ... -
Free Shear Layer Behavior in Rotating Systems
(The American Society of Mechanical Engineers (ASME), 1979)Experiments are reported concerning turbulent separated flow downstream of a backward-facing step in a two-dimensional channel that was rotated at a steady rate about a spanwise axis. Reattachment ... -
Use of Electrochemical Methods for the Study of Mass Transfer and Drag Reduction in Polymer Solutions Close to a Wall
(The American Society of Mechanical Engineers (ASME), 1979)Mass transfer to the surface of a rotating disk in the presence of a drag reducing polymer (PEO) has been studied by an electrochemical method. Mass transfer rates were predicted and measured ... -
A Probe for the Measurement of the Velocity Field
(The American Society of Mechanical Engineers (ASME), 1979)A convenient method for the measurement of the complete velocity vector in subsonic three-dimensional flow using a simple three-tube off set-geometry pressure probe is presented. Basically, this ... -
An Integral Method for Calculating Turbulent Boundary Layer With Separation
(The American Society of Mechanical Engineers (ASME), 1979)A two-equation energy integral boundary layer method is presented for the calculation of separation and of slightly separated boundary layers. The method is a direct one and is capable of ... -
Laminar Throughflow of a Fluid Containing Particles Between Corotating Disks
(The American Society of Mechanical Engineers (ASME), 1979)The flow between corotating disks is the basic flow in multiple-disk turbomachinery and such turbomachinery can be used with possible advantage with dusty gases. An analysis is presented which ... -
Jet Pump Cavitation With Ambient and High Temperature Water
(The American Society of Mechanical Engineers (ASME), 1979)Cavitation characteristics of a jet pump were explored in tests with 80°C and 280°C water. A cavitation coefficient based on suction velocity and net suction head was used to correlate ... -
Velocity Exponent for Erosion and Noise Due to Cavitation
(The American Society of Mechanical Engineers (ASME), 1979)The aim of the present study was to evaluate the effects of flow velocity on erosion and noise due to cavitation. To this end, tests were conducted in a two-dimensional water tunnel in which ... -
Isothermal, Compressible-Gas Flow in Horizontal Pipes With an Imperfect Gas
(The American Society of Mechanical Engineers (ASME), 1979)A method for calculating pressure drop, based on a three parameter “law” of corresponding states, is developed rigorously from thermodynamic and fluid dynamic principles. A pressure correction ... -
Transport of Oils as Oil-in-Water Emulsions
(The American Society of Mechanical Engineers (ASME), 1979)Turbulent flow pressure drop measurements were made for various concentrated oil-in-water emulsions which exhibit non-Newtonian behavior. The effects of oil viscosity, temperature and oil concentration ... -
Fillet Size in a Liquid Jet
(The American Society of Mechanical Engineers (ASME), 1979)As a liquid jet is formed by a nozzle, a fillet, wetting the outside face of the nozzle, can exist at appropriate jet velocities. The lack of azimuthal symmetry in such a fillet adversely ... -
The Effect of Gaseous Cavitation on Fluid Transients
(The American Society of Mechanical Engineers (ASME), 1979)Gaseous cavitation, alternately termed gas release, is investigated for turbulent pipe flows subjected to transient wave motion. Experimental data are presented that exhibit developing two-component ... -
Compressibility Effects in Cavity Flows
(The American Society of Mechanical Engineers (ASME), 1979)The aim of this paper is to present the compressibility effects in cavity flows in the case of Joukowsky-Roshko model in a channel for a wedge shaped obstacle. In virtue of some exact ... -

The 1978 Freeman Scholar Lecture: Buoyancy Induced Fluid Motions Characteristic of Applications in Technology
(The American Society of Mechanical Engineers (ASME), 1979)Buoyancy induced flows abound in nature and in our enclosures and devices. They arise through the interaction of a body force, like gravity, with a density difference. The difference is often ... -
Pressure Pulse Propagation in Two-Component Slug Flow
(The American Society of Mechanical Engineers (ASME), 1979)The simple model of pressure pulse propagation in slug flow proposed by Henry, Grolmes, and Fauske has been extended by considering wave reflection and wave transmission at gas-liquid interfaces. ...
