Wake Flow Stabilization by the Action of Base Bleed
(The American Society of Mechanical Engineers (ASME), 1985)Experimental investigation into the effects of base bleed on wake stabilization for the suppression of flow-induced oscillation has shown that when the bleed flow rate is increased, the initial ... -
Flow Formed by Spanwise Gaps Between Roughness Elements
(The American Society of Mechanical Engineers (ASME), 1985)Measurements of the three mean velocity components and the three Reynolds shear stresses were made in the region downstream of gaps between wall-mounted roughness elements of square cross section ... -
Pressure Distribution for Radial Inflow Between Narrowly Spaced Disks
(The American Society of Mechanical Engineers (ASME), 1985) -
Higher Velocity Resonance of Circular Cylinder in Crossflow
(The American Society of Mechanical Engineers (ASME), 1985)This report concerns the oscillation of an elastically supported circular cylinder in a uniform crossflow. Several investigators have observed an unexpected subharmonic-like resonance at f v /f ... -
Boundary-Layer Control as a Means of Reducing Drag on Fully Submerged Bodies of Revolution
(The American Society of Mechanical Engineers (ASME), 1985)The drag of axisymmetric bodies can be reduced by boundary-layer suction, which delays transition and can control separation. In this study, boundary-layer transition is delayed by applying a ... -
The Formation of Stratified Combustible Mixtures in Closed Tubes by Molecular and Convective Diffusions
(The American Society of Mechanical Engineers (ASME), 1985)This paper describes a theoretical study on the formation of stratified combustible mixtures in closed long vertical flame tubes. The concentration profiles of the fuel (methane) in air, just ... -
A Flow Visualization Study of a Square Array of Tubes in Water Crossflow
(The American Society of Mechanical Engineers (ASME), 1985)A flow visualization technique has been developed to study the flow behavior in tube arrays in water crossflow. The technique is used to examine flow development in a square array with a ... -
The Influence of Pipe Motion on Acoustic Wave Propagation
(The American Society of Mechanical Engineers (ASME), 1985)It is well known that the magnitude of the acoustic wavespeed in piping is influenced by properties of the fluid and the pipe material. Traditionally, derivations have been based on a ... -
An Investigation of Compressible Flow Characteristics of Butterfly Valves
(The American Society of Mechanical Engineers (ASME), 1985)Compressible flow characteristics including mass flowrate, onset of “choked” flow, stagnation pressure loss, and static pressure recovery have been investigated for butterfly valves. A simplified ... -
A Semipotential Flow Theory for the Dynamics of Cylinder Arrays in Cross Flow
(The American Society of Mechanical Engineers (ASME), 1985)This paper presents a semianalytical model, involving the superposition of the empirically determined cross flow about a cylinder in an array and the analytically determined vibration-induced flow ... -
Flow Around Two Intersecting Circular Cylinders
(The American Society of Mechanical Engineers (ASME), 1985)One aspect of the flow around two intersecting cylinders, which has attracted little attention so far, is the structure of a three-dimensional near-wake behind the intersection. Some preliminary ... -
Second-Order Accurate Explicit Finite-Difference Schemes for Waterhammer Analysis
(The American Society of Mechanical Engineers (ASME), 1985)Three second-order accurate explicit finite-difference schemes—MacCormack’s method, Lambda scheme and Gabutti scheme—are introduced to solve the quasilinear, hyperbolic partial differential equations ... -
Stable Floating Drops of Liquid
(The American Society of Mechanical Engineers (ASME), 1985)There are few reported situations in which a drop of liquid will remain intact in ambient conditions for an indefinite period of time. The paper describes a situation where this happens. The ... -
Unsteady Flow in a Porous Medium Between Two Infinite Parallel Plates in Relative Motion
(The American Society of Mechanical Engineers (ASME), 1985)An approximate solution to the unsteady flow of a viscous incompressible fluid through a porous medium bounded by two infinite parallel plates, the lower one stationary and the upper one ... -

Adaptive Grid Generation by Mean Value Relaxation
(The American Society of Mechanical Engineers (ASME), 1985)A grid movement algorithm has been developed for the purpose of adaptively resolving numerical solutions to physical problems and, in addition, for grid clustering on arbitrary surfaces. Both ... -
The Flow Over Two-Dimensional Surface-Mounted Obstacles at Low Reynolds Numbers
