A close-form model for dispersion in shallow waves over varying shear current
Longitudinal dispersion coefficient waves steady shear
2010/9/26
The longitudinal dispersion coefficient of pollutants in a wave-steady current flow field (WCLDC) is theoretically quantified by deriving a stream function for the combined flow. The steady current pr...
Adomian decomposition method for dispersion phenomena arising in longitudinal dispersion of miscible fluid flow through porous media
Adomian Decomposition method Miscible fluid
2010/11/25
In this paper a theoretical model is developed for the dispersion problem in porous media in which the flow is one dimensional and the average flow is unsteady. The Numerical Solution and graphical il...
On dispersion of pollutants in initial unsteady phase
Diffusivity longitudinal dispersion coefficient

In the initial unsteady phase of mixing, the tidal oscillatory velocity [1st order in wave amplitude (a) ] provides finite longitudinal dispersion for moderate to short period oscillations (Fischer et...
