Estimation of unsaturated flow in layered soils with the finite control volume method
(2001)Water movement in unsaturated soil is described by Richards' equation, which is strongly nonlinear and cannot be solved analytically. For this reason numerical methods such as finite difference and finite element methods ... -
Gaseous mixture flow between two parallel plates in the whole range of the gas rarefaction
(2004)The flow of binary gaseous mixtures between two parallel plates driven by gradients of pressure, temperature and concentration is studied, based on the McCormack model of the Boltzmann equation. The coupled kinetic equations ... -
Lattice kinetic simulations in three-dimensional magnetohydrodynamics
(2004)A lattice kinetic algorithm to simulate three-dimensional (3D) incompressible magnetohydrodynamics is presented. The fluid is monitored by a distribution function, which obeys a scalar kinetic equation, subject to an ... -
Nonlinear resonance in viscous films on inclined wavy planes
(2009)We study nonlinear resonance in viscous gravity-driven films flowing over undulated substrates. Numerical solution of the full, steady Navier-Stokes equations is used to follow the emergence of the first few free-surface ... -
Optimization of extrapolated Cayley transform with non-Hermitian positive definite matrix
(2014)For the extrapolated Cayley transform, we give necessary and sufficient conditions for guaranteeing its convergence and contraction (in the Euclidean norm). We derive upper bounds for the convergence and the contraction ... -
Solitary waves on inclined films: Flow structure and binary interactions
(2002)The downstream evolution of disturbances, introduced at the inlet of a liquid film flowing along an inclined plane wall, is studied numerically by solving the full, time-dependent Navier-Stokes equation. Computational ... -
Theoretical and Experimental Research of Cumulative Infiltration
(2013)The main object of this study is the comparative evaluation of Green & Ampt's (G & A) and Parlange's (P's) models and their ability to describe cumulative infiltration of water through various soil types. Three soil samples ...
