This paper addresses the development of equations for nonlinear dispersive waves that have improved stability properties over the commonly used Boussinesq-type equations. Boussinesq-type...

The Influence of the Viscosity on the Progressive Waves
In a stationary atmosphere, the free-surface progressive wave motion in a real fluid of uniform depth is analysed by using Navier-Stokes equation, and its mechanism is described in first-order...

Comparative Performance of Spectral and Parametric Numerical Wave Prediction Models in Lake Michigan
Four different numerical wave prediction models are used to hindcast wave conditions in Lake Michigan for a 10 day case in October, 1988. Results are compared to observed wave height and...

The CYCLE 2 version of the WAM (Wave Model) model is used to hinfcast global ocean wave spectra, using the NMC (National Meteorological Center) winds, for a period of about 60 days. The...

Gas Phase Turbulence Modification with Fine Particles in 2-D Duct Flow
The effect of a dilute suspension of fine particles on a two-dimensional turbulent duct gas flow is measured with hot-film anemometry. The flow field without particles is compared to the...

Computation of Flow Fields Induced by Hydroplant Releases into Lower Lock Approaches
A turbulence-based computational procedure was developed and applied to the prediction of flow fields in navigation installations induced by hydropower releases. The procedure uses a depth-averaged...

Hydrodynamic Pressure on an Oscillating Vertical Plate
The hydrodynamic pressure on an oscillating vertical plate could be influenced by the effects of compressibility of fluids and surface waves. The compressibility is effective for higher...
