ETUDE DU TRANSFERT DES PARTICULES SOLIDES DANS LES EAUX SOUTERRAINES (MODELISATION AU LABORATOIRE)
Journal Title: Larhyss Journal - Year 2015, Vol 22, Issue 22
Abstract
The work carried out in this article relates to two sandy formations of physical characteristics (porosity, permeability, porous volume) different. Also, two types of tracers in suspended particles (clays and lime). The suspended particles are implied in many problems; such as the hydraulic works, the exploitation of the underground resources (hydrous and oil), the transport of the latter in water can be a vector of transport of contaminants or brakes by their deposition (filling of the pores).The experimental studies of transport in suspension and their deposition in our experimental column, were carried out in a laminar mode. The interpretation of the results of tracing obtained by using the equation convection-dispersion of first order; we allowed to determine the various parameters hydrodispersive. The various rates of flow used and cuts in particles are parameters which influence on transport and deposition. The rate of refund is function of the rate of flow and the porosity of the medium.
