Improved methods for thin, surface boundary layer investigations
(Springer-Verlag; Springer-Verlag Berlin Heidelberg, 1998-10)
New techniques are developed to improve the velocity flow-field measurement capability within a free-surface boundary layer region on which progressive capillary-gravity waves are present. Due to the extremely thin but ...
High speed digital imaging of cavitating vortices
(Springer-Verlag; Springer-Verlag Berlin Heidelberg, 1998-05)
Researchers at the Cavitation and Multiphase Flow Laboratory of the University of Michigan worked in conjunction with Princeton Scientific Instruments (PSI) engineers to employ a new digital imaging system in the study ...
Nonisothermal model of glass fiber drawing stability
(Steinkopff-Verlag; Springer Science+Business Media, 1996-11)
Draw resonance is caused by a constant speed winder that leads to non-constant axial forces (Schultz, 1984). The well studied isothermal Newtonian fiber drawing predicts very modest critical draw ratios (around 20, much ...
Solution of potential problems using an overdetermined complex boundary integral method
(Elsevier, 1989-10)
The advantages of solving potential problems using an overdetermined boundary integral element method are examined. Representing a 2-dimensional potential solution by an analytic complex function forms two algebraic systems ...
Singularity image method for electrical impedance tomography of bubbly flows
(IOP Publishing Ltd, 2003-08-01)
A singularity image method is applied to the electrical impedance tomography of gas–liquid flows in a two-dimensional circular domain. Algorithms that use analytic complex functions, dipoles and the Milne-Thomson circle ...
High Reynolds number experimentation in the US Navy's William B Morgan Large Cavitation Channel
(IOP Publishing Ltd, 2005-09-01)
The William B Morgan Large Cavitation Channel (LCC) is a large variable-pressure closed-loop water tunnel that has been operated by the US Navy in Memphis, TN, USA, since 1991. This facility is well designed for a wide ...
Spectral method solution of the Stokes equations on nonstaggered grids
(Elsevier, 1991-05)
The Stokes equations are solved using spectral methods with staggered and nonstaggered grids. Numerous ways to avoid the problem of spurious pressure modes are presented, including new techniques using the pseudospectral ...
Stability of fluid in a rectangular enclosure by spectral method
(Elsevier, 1989-03)
The hydrodynamic stability of Rayleigh convection in a rectangular cavity is studied numerically. The calculation assumes that the Boussinesq fluid motion is two-dimensional. The characteristic value equations are solved ...
An efficient finite element method for treating singularities in Laplace's equation
(Elsevier, 1991-10)
We present a new finite element method for solving partial differential equations with singularities caused by abrupt changes in boundary conditions or sudden changes in boundary shape. Terms from the local solution ...
Velocity field measurements of cavitating flows
(Springer-Verlag, 1995-12)
A particle Image Velocimetry (PIV) system has been developed to study the microfluid mechanics of cavitating flows. Planar PIV was used to examine the non-cavitating flow in the thin boundary layer near a hydrofoil surface ...
