Flows Generated by the Impingement of a Jet on a Rotating Surface: Part I—Basic Flow Patterns
(The American Society of Mechanical Engineers (ASME), 1996)The results of an experimental study of the flow field resulting from the interaction between an impinging jet and a rotating disk are presented. The resulting flow configuration has applications ... -
Flows Generated by the Impingement of a Jet on a Rotating Surface: Part II—Detailed Flow Structure and Analysis
(The American Society of Mechanical Engineers (ASME), 1996)In Part I of this investigation, the basic flow patterns resulting from the interaction of a turbulent jet and a rotating disk flow were presented paying particular attention to mean and ... -
Unsteady Heat Transfer From a Sphere at Small Peclet Numbers
(The American Society of Mechanical Engineers (ASME), 1996)In a recent paper by Michaelides and Feng (1994) it was discovered that there are history terms in the unsteady heat conduction equation from a small sphere. The history terms are analogous ... -
Numerical Study of an Unsteady Confined Jet. Application to Crossflow Filtration
(The American Society of Mechanical Engineers (ASME), 1996)This paper deals with the influence of a new flow unsteadiness on the permeate flux in crossflow filtration. A pneumatically controlled valve generates intermittent jets from the main flow, ... -
Influences of Fluidic Interfaces on the Formation of Fine Scale Structure by Chaotic Mixing
(The American Society of Mechanical Engineers (ASME), 1996)A numerical model has been developed of two-dimensional chaotic mixing of immiscieble Newtonian fluids. A computationally efficient numerical methodology is employed which is well-suited to complex, ... -
Laminar Fluid Flow in a Planar 90 Degree Bifurcation With and Without a Protruding Branching Duct
(The American Society of Mechanical Engineers (ASME), 1996)The laminar flow field in a planar, ninety degree bifurcation is examined. This numerical study uses the computational-fluid-dynamics software Fluent Version 4.11. First, the velocity field in a ... -
On the Virtual Nonexistence of Multiple Instability Regions for Some Heat-Exchanger Arrays in Crossflow
(The American Society of Mechanical Engineers (ASME), 1996)In fluidelastic analyses involving a time delay (or phase lag) between the motions of cylinders in an array and the resultant unsteady fluid forces on the cylinders, a succession of ... -
Particle Dispersion in Flowing Gases—1994 Freeman Scholar Lecture
(The American Society of Mechanical Engineers (ASME), 1996) -
Frequency Dependence of Mass Flow Gain Factor and Cavitation Compliance of Cavitating Inducers
(The American Society of Mechanical Engineers (ASME), 1996)Unsteady cavitation characteristics are analyzed based on a closed cavity model in which the length of the cavity is allowed to oscillate. It is shown that the present model blends smoothly ... -

Wall Suction Effects on the Structure of Fully Developed Turbulent Pipe Flow
(The American Society of Mechanical Engineers (ASME), 1996)The effects of wall suction on the structure of fully developed pipe flow are studied numerically by solving the Reynolds averaged Navier-Stokes equations. Linear and nonlinear k-ε or k-ω low-Re ... -
Sources of Error in Eigenvalue Spectra for Pipe-Poiseuille Flows
(The American Society of Mechanical Engineers (ASME), 1996)An operational Chebyshev Tau approach was used to establish temporal eigenvalue stability spectra for pipe-Poiseuille flows, using the Sexl equation which was transformed to remove the singularity ... -
A Review of Electrical Impedance Techniques for the Measurement of Multiphase Flows
(The American Society of Mechanical Engineers (ASME), 1996)Various developments in the use of electrical impedance methods in multiphase flow are reviewed. Because the components of a multiphase flow often exhibit different electrical properties, a variety ... -
