Calculation of Laminar Separated Flow in Symmetric Two-Dimensional Diffusers
(The American Society of Mechanical Engineers (ASME), 1995)This study is concerned with numerical analysis of laminar separated flow in symmetric, two-dimensional, straight-walled diffusers. With Reynolds numbers Re = 56 and 114 and expansion ratios ER ... -
Velocity and Turbulence Characteristics of Isothermal Lobed Mixer Flows
(The American Society of Mechanical Engineers (ASME), 1995)This work describes an experimental and computational study of flows in model multilobed mixers. Laser Velocimetry was used to obtain the velocity and turbulence fields in the downstream mixing ... -
Three-Dimensional Chaotic Mixing of Fluids in a Cylindrical Cavity
(The American Society of Mechanical Engineers (ASME), 1995)Three-dimensional chaotic mixing of Newtonian fluids in a previously uninvestigated cylindrical cavity was studied both experimentally and numerically for creeping flow conditions. Such mixing ... -
Implications of Correlated Bias Uncertainties in Single and Comparative Tests
(The American Society of Mechanical Engineers (ASME), 1995)The effects of correlated bias uncertainties are considered for both single and comparative tests, and the implications of these effects on experimental results and their uncertainties are ... -
Assessment of a Reynolds Stress Closure Model for Appendage-Hull Junction Flows
(The American Society of Mechanical Engineers (ASME), 1995)A multiblock numerical method, for the solution of the Reynolds-Averaged Navier-Stokes equations, has been used in conjunction with a near-wall Reynolds stress closure and a two-layer isotropic ... -
The Effect of Constriction Size on the Pulsatile Flow in a Channel
(The American Society of Mechanical Engineers (ASME), 1995)The effect of the constriction size on the pulsatile flow in a channel is studied by solving the time-dependent incompressible Navier-Stokes equations. A pulsating incoming flow is specified at ... -
The Interaction of Rolling Vortices With a Turbulent Boundary Layer
(The American Society of Mechanical Engineers (ASME), 1995)Laser-Doppler velocimetry is employed to measure the periodic field created by releasing spanwise vortices in a turbulent boundary layer. Phase-averaged vorticity and turbulence level contours are ... -
Prediction of Compressible Flow Pressure Losses in 30–150 Deg Sharp-Cornered Bends
(The American Society of Mechanical Engineers (ASME), 1995)This paper considers the measurement and prediction of the additional total pressure losses of subsonic steady air flow in sharp-cornered bends, similar to those present in the secondary air ... -
Testing Three-Dimensional Bluff-Body Models in a Low-Speed Two-Dimensional Adaptive Wall Test Section
(The American Society of Mechanical Engineers (ASME), 1995)Thin, sharp-edged disk models were evaluated in a low-speed two-dimensional adaptive flexible wall test section to determine the optimum adaptive wall testing environment for three-dimensional ... -
An Experimental Study of Pulsatile Flow in Canine Larynges
(The American Society of Mechanical Engineers (ASME), 1995)Pulsatile flow in an excised canine larynx was investigated with simultaneous recordings of air velocity, subglottal pressure, volume flow rate, and the signal from an electro-glottograph (EGG) ... -

Torque Produced by Misalignment of Hydrodynamic Gas-Lubricated Journal Bearings
(The American Society of Mechanical Engineers (ASME), 1960)A perturbation analysis is used to find the torque generated by a misaligned journal bearing (or, equivalently, to find the angular displacement of a torque-loaded journal). Results are presented ... -
Bearing Oil-Ring Performance
(The American Society of Mechanical Engineers (ASME), 1960)A series of tests was made with rings ranging from 2 3/4 to 16 1/2 in. ID and at journal speeds up to 4000 fpm. Correlation of the results provides means for calculating ring speed for ... -
A Sommerfeld Solution for Finite Bearings With Circumferential Grooves
(The American Society of Mechanical Engineers (ASME), 1960)A method of solution is developed that circumvents the algebraic complexity in the solution of Reynolds differential equation applied to full journal bearings. The method leads to equations for ... -
A General Theory for Elastically Constrained Ball and Radial Roller Bearings Under Arbitrary Load and Speed Conditions
(The American Society of Mechanical Engineers (ASME), 1960)A completely general solution is obtained whereby the elastic compliances of a system of any number of ball and radial roller bearings under any system of loads can be determined. Elastic ... -
