The variation in moisture content between subsequent irrigations determines the use of infiltration equations that contain representative physical parameters soil when irrigation begins. This study analyzes reliability hydrodynamic model to simulate advanced phase border irrigation. For solution model, a Lagrangian scheme implicit finite differences is used, while for infiltration, Kostiakov eq...

There is an increasing demand for knowledge about hydrodynamic, morphological and water quality processes within the estuarine waterways of the Gold Coast. This study describes the development of a suite of hydrodynamic, sediment transport and water quality models for the Gold Coast tidal waterways. The modeling framework described was developed to provide a strategic understanding of waterway ...

A new formulation employing the Galerkin/least-squares finite element method is presented for the simulation of the hydrodynamic model of semiconductor devices. Numerical simulations are performed on the coupled Poisson and hydrodynamic equations for one carrier devices. The hydrodynamic equations for a single carrier, i.e. for the electrons or holes, resemble the compressible Navier-Stokes equ...

The proposed Adhesion-Deformation-Hydrodynamic model of friction and wear is based on the relationship elastic-deformation processes in surfaces curvilinear contacts with hydrodynamic regular extrusion rarefaction lubricating layers tribocontacts, as well primary adhesion subsequent acts adhesive wear. its main provisions between extrusion, cover entire load-speed range all modes lubrication

A new derivation of the velocity correlations of a thermally fluctuating Brownian particle is shown by direct calculation from a stochastic hydrodynamic model in which the fluid-particle coupling is treated in a simple manner. The model significantly simplifies the calculation of statistics of a particle and has the virtue of being readily amenable to numerical simulation. To show that the mode...

The new method proposed in this work not only measures the particle size distribution and the average molar mass accurately using the static light scattering (SLS) technique when the Rayleigh-Gans-Debye approximation is valid for dilute poly-disperse homogenous spherical particles in dispersion, but also enables us to have insight into the theoretical analysis of the dimensionless shape paramet...
