Evaluation of overshooting errors in particle methods for diffusion by biased global random walk
AbstractThe adjustment of grid steps which guarantees that particles methods yield no numerical diffusion inevitably induces overshooting errors in the…

Itô equation model for dispersion of solutes in heterogeneous media
AbstractTransport processes in heterogeneous media such as ionized plasmas, natural porous media, and turbulent atmosphere are often modeled as diffusion…
Laguerre collocation solutions vs. analytic results for singular semilinear BVPs on the half line
AbstractWe make use of two Laguerre collocation techniques as a way to illustrate, deepen or extend some analytic results of…
Numerical simulation of rain-runoff process within the Zalău drainage, at the Sărmăşag gauging point
AbstractWe use the rainfall-runoff model of Nielsen and Hansen in order to study the daily rates of flow at the…
The shooting method in establishment of concentration profiles in diffusive boundary layer
AbstractA viscous incompressible fluid reacts chemically with a rotating disk. We establish the diffusion equation in the boundary layer corresponding…
Marangoni flow -induced by temperature gradients- against gravity forces
AbstractIn the present work a comparison in made between the authors’ experimental and numerically calculated data obtained in studying the…
On the behavior of a thin liquid layer flowing due to gravity and a surface tension gradient
AbstractA thin liquid layer flowing due to gravity and a surface tension gradient is taken into account. On the liquid/gas…
Surface mobility of surfactant solutions XVII. Determination of Marangoni rate of flow in simulated zero gravity conditions
