Preston-Static Tubes for the Measurement of Wall Shear Stress
(The American Society of Mechanical Engineers (ASME), 1994)We present a Preston tube device that combines both total and static pressure readings for the measurement of wall shear stress. As such, the device facilitates the measurement of wall shear ... -
Estimating Uncertainty in Computations of Two-Dimensional Separated Flows
(The American Society of Mechanical Engineers (ASME), 1994)The present paper investigates sources of uncertainties in two-dimensional flow computations and presents methods for estimating them. A sample problem is used for illustration. The following ... -
Perspective: Future Research Directions in Computational Fluid Dynamics
(The American Society of Mechanical Engineers (ASME), 1994)The current state of computational fluid dynamics (CFD) has yet to reach its full promise as a general tool for engineering design and simulation. Research in the areas of code robustness, ... -
Optimum Suppression of Fluid Forces Acting on a Circular Cylinder
(The American Society of Mechanical Engineers (ASME), 1994)The objective of this paper is to investigate the suppression of the fluid forces acting on a circular cylinder (hereafter called the main cylinder) by controlling the flow around it. Flow ... -
Three-Dimensional Recirculation Flow in a Backward Facing Step
(The American Society of Mechanical Engineers (ASME), 1994)The flow field behind a small aspect ratio (channel width/step height = 3) backward-facing step is examined using laser Doppler anemometer. All three velocity components inside the separation ... -
Flow in a Channel With Longitudinal Ribs
(The American Society of Mechanical Engineers (ASME), 1994)The laminar, viscous flow between parallel plates with evenly spaced longitudinal ribs is solved by an eigenfunction expansion and point-match method. The ribs on both plates may be symmetrically ... -

Phase Distribution of High-Pressure Steam-Water Flow at Large-Diameter Tee Junctions (Data Bank Contribution)
(The American Society of Mechanical Engineers (ASME), 1994)Experimental data are presented for the phase distribution of high pressure (2.75 to 5.5 MPa) steam-water mixtures at horizontal, equal-sided dividing tee junctions of two different sizes (49.3 ... -
An Experimental Investigation of Throughflow Velocities in Two-Dimensional Fluidized Bed Bubbles: Laser Doppler Anemometer Measurements
(The American Society of Mechanical Engineers (ASME), 1994)Detailed nonintrusive measurements have been made to determine the throughflow velocity in isolated fluidized bed bubbles. In air-fluidized beds, the throughflow component has been rather neglected ... -
The Effect of Interfacial Waves on the Transition to Slug Flow
(The American Society of Mechanical Engineers (ASME), 1994)It has been proposed by the authors that the transition to slug flow depends on the growth of waves in the two-phase flow and thus may predict if the laws of wave growth in closed channel ... -
A Numerical Treatment for Attached Cavitation
(The American Society of Mechanical Engineers (ASME), 1994)A new numerical treatment has been developed for the prediction of the flowfield resulting from an attached cavitation region. The cavitation model has been implemented in a viscous calculation ... -
