Effects of Free-Stream Turbulence on Diffuser Performance
(The American Society of Mechanical Engineers (ASME), 1981)An experimental evaluation of the effects of free-stream turbulence on the performance of a subsonic two-dimensional diffuser has been made. Increases of the diffuser’s static pressure recovery ... -
Experimental and Theoretical Study of Surge in a Small Centrifugal Compressor
(The American Society of Mechanical Engineers (ASME), 1981)Experimental results for deep surge in a small single-stage centrifugal compressor are compared to predictions based on the lumped parameter Greitzer model developed for axial compressors. Both ... -
Viscous Flow Drag Reduction (Progress in Astronautics and Aeronautics, Vol. 72)

Review—Basic Research Needs in Fluid Mechanics
(The American Society of Mechanical Engineers (ASME), 1981)A small segment of the engineering community was surveyed to obtain their judgment regarding the long-range needs for basic research in fluid mechanics. This segment consisted of approximately ... -
Review—A Review of Some Phenomena in Turbulent Flow Separation
(The American Society of Mechanical Engineers (ASME), 1981)Although turbulent flow separation is an old topic, little credible information is available on the flow details that must be understood to predict flows of this type. Until the last decade, ... -

A Possible Criterion for Cavitation Inception on Hemispherical Headforms
(The American Society of Mechanical Engineers (ASME), 1981)The present paper reviews several pertinent papers about the onset of bubble-ring cavitation on hemispherical headforms in which a laminar bubble is present. From this review, a likely sequence ... -
A Four Hole Pressure Probe for Fluid Flow Measurements in Three Dimensions
(The American Society of Mechanical Engineers (ASME), 1981)A pressure probe which facilitates measurement of mean flow quantities in three dimensions simultaneously is described. Its main feature is a tip shaped like the frustrum of a pyramid, with ... -
Velocity Field and Entrainment of a Pulsed Core Jet
(The American Society of Mechanical Engineers (ASME), 1981)A pulsed core jet is one consisting of a steady annular flow with a core, the mass flow of which is unsteady. The combined jet exhausts into a still environment. The velocity field and ... -
Generation of Oscillating Jets
(The American Society of Mechanical Engineers (ASME), 1981)It is shown that periodic angular oscillations can be forced on a jet issuing from a nozzle based on the Coanda effect by alternate blowing from the two sides. The influence of the various ... -
Liquid Sheet Jet Experiments: Comparison With Linear Theory
(The American Society of Mechanical Engineers (ASME), 1981)It has been proposed to protect the structural walls of a future laser fusion reactor with a curtain or fluid-wall of liquid lithium jets. As part of the investigation of this concept, ... -
