Pressure Losses in Smooth Pipe Bends
(The American Society of Mechanical Engineers (ASME), 1960)The results of extensive experimental studies to determine the pressure losses for turbulent flow in smooth pipe bends of circular cross section are presented in this paper. To make the data ... -
Investigation and Control of Backflow Ahead of a Shrouded Inducer
(The American Society of Mechanical Engineers (ASME), 1998)Incorporating a backflow recirculator is a way to reduce part load instabilities of inducers. Experimental results demonstrate that two devices with simple geometry considerably soften pressure ... -
Performance and Design of Straight, Two-Dimensional Diffusers
(The American Society of Mechanical Engineers (ASME), 1967)Performance data and flow characteristics for subsonic, two-dimensional, straight center line diffusers are presented. The four primary flow regimes which can occur are described and presented as ... -
A New Approach to the Reduction of Pump Cavitation: The Hubless Inducer
(The American Society of Mechanical Engineers (ASME), 1967)This paper describes a new and promising inducer which has no hub but a shroud. The design makes it possible to employ drastic vane sweepback. The shroud eliminates the vane clearance cavitation ... -
Three-Dimensional Laminar Flow in a Rotating Multiple-Pass Square Channel With Sharp 180-Deg Turns
(The American Society of Mechanical Engineers (ASME), 1998)This paper presents a study of three-dimensional laminar flow in a rotating multiplepass channel connected with 180-deg sharp bends. Fluid-flow fields are calculated for the entire domain via ... -
Methods to Set Up and Investigate Low Reynolds Number, Fully Developed Turbulent Plane Channel Flows
(The American Society of Mechanical Engineers (ASME), 1998)The tripping of fully developed turbulent plane channel flow was studied at low Reynolds number, yielding unique flow properties independent of the initial conditions. The LDA measuring technique ... -
A Methodology for Determining Experimental Uncertainties in Regressions
(The American Society of Mechanical Engineers (ASME), 1998)A methodology to determine the experimental uncertainties associated with regressions is presented. When a regression model is used to represent experimental information, the uncertainty associated ... -
Flowfield Investigation of the Effect of Rib Open Area Ratio in a Rectangular Duct
(The American Society of Mechanical Engineers (ASME), 1998)The spatially periodic turbulent fluid flows and friction in a rectangular passage of width-to-height ratio of 4:1 with perforated rectangular ribs mounted on one wall have been studied using ... -
Numerical Study of Oscillation Mechanism in Underexpanded Jet Impinging on Plate
(The American Society of Mechanical Engineers (ASME), 1998)The mechanism of the oscillatory phenomena of an underexpanded jet impinging on a flat plate is studied numerically. Pressure changes generated in the flow field near the plate propagate radially ... -

Perspective: Flow at High Reynolds Number and Over Rough Surfaces—Achilles Heel of CFD
(The American Society of Mechanical Engineers (ASME), 1998)The law of the wall and related correlations underpin much of current computational fluid dynamics (CFD) software, either directly through use of so-called wall functions or indirectly in near-wall ... -
High-Speed PIV Analysis Using Compressed Image Correlation
(The American Society of Mechanical Engineers (ASME), 1998)With the development of Holographic PIV (HPIV) and PIV Cinematography (PIVC), the need for a computationally efficient algorithm capable of processing images at video rates has emerged. This ... -
