The Effects of an Annular Fluid on the Vibrations of a Long Rotor, Part 2—Test
(The American Society of Mechanical Engineers (ASME), 1970)Analyses and tests were made to investigate the hydrodynamic mass and damping of a fluid in a thin annulus surrounding a rotor which is vibrating due to unbalance forces. The analysis is ... -
The Effects of an Annular Fluid on the Vibrations of a Long Rotor, Part 1—Theory
(The American Society of Mechanical Engineers (ASME), 1970)Analysis and tests were made to investigate the hydrodynamic mass and damping effects of a liquid in a thin annulus surrounding a vibrating rotor. The analytical results are described in this ... -
Some Solutions of the Plane Turbulent Impinging Jet
(The American Society of Mechanical Engineers (ASME), 1970)The impinging jet problem is solved by an iterative finite-difference technique. Reynolds stresses are assumed to be related to the mean strain by a scalar eddy viscosity. The eddy viscosity ... -
Analysis of Flow Separation in a Confined Two-Dimensional Channel
(The American Society of Mechanical Engineers (ASME), 1970)A two-dimensional incompressible isothermal laminar separation of a Newtonian fluid in steady flow was investigated. The geometry chosen for this study was a constant-width channel with a sharp ... -
Interaction of a Two-Dimensional Sonic Jet With a Supersonic Stream
(The American Society of Mechanical Engineers (ASME), 1970)Experiments were conducted in a 1-in. × 3-in. supersonic wind tunnel on two-dimensional secondary fluid injection into a uniform primary supersonic stream. Both primary and secondary fluids ... -
An Analytical and Experimental Study of a Vortex Pump
(The American Society of Mechanical Engineers (ASME), 1970)A pump which operates by setting up a vortex in a chamber in front of the impeller is often called a vortex pump. Vortex pumps by virtue of this design have a large free and open flow ... -
On Nonuniform Flow Characteristics at the Vena Contracta
(The American Society of Mechanical Engineers (ASME), 1970)The kinetic energy correction factor for the flow at the vena contracta is calculated using experimental data and a modified Bernoulli equation. Based on an assumption of similarity of the ... -
Fluid Transient and Heat Flows in Screw Viscosity Pumps
(The American Society of Mechanical Engineers (ASME), 1970)It is the objective of this paper to investigate the dynamic response of fluid and heat flows in screw viscosity pumps so that their performance may be correctly and easily predicted, the ... -
A Boundary-Layer Theory for Transient Viscous Losses in Turbulent Flow
(The American Society of Mechanical Engineers (ASME), 1970)A laminar boundary-layer model is proposed to account for viscous losses during the transient turbulent flow of a liquid in a tube. In this model, inviscid slug flow is assumed for the core ... -
Mechanism of Slug Formation in Horizontal Two-Phase Flow
(The American Society of Mechanical Engineers (ASME), 1970)It is proposed in this work that the transition to slug flow occurs due to Kelvin-Helmholtz instability, which, in this case, is enhanced by the proximity of the upper wall and becomes ... -
Experimental Study of Through-Flowing Pneumatic Lines
(The American Society of Mechanical Engineers (ASME), 1970)The complete linear two-port admittance parameters of a short uniform pneumatic line are experimentally determined as functions of driving frequency and the steady through-flow in the line. The ... -
Experiments on Coupled Parallel Flows in a Channel and a Bounding Porous Medium
(The American Society of Mechanical Engineers (ASME), 1970)Experiments were performed to study the laminar flow characteristics and the laminar-turbulent transition in a parallel-plate channel, one of whose bounding walls is a porous medium. The flow ... -
