The phenomenon of imbibition is great importance in the petroleum industry. In this analysis, we have studied Counter-current through mathematical modelling a double non-miscible phase vertical heterogeneous porous medium, which ensues process oil recovery. non-linear partial differential equation second-order result formulation. Variational iteration approach applied to attain approximate anal...

Grafting of vinyl monomers onto cellulose is an important tool for the modification of cellulose. Depending on the monomer grafted onto cellulose, it gains new properties. The grafting can be performed in heterogeneous or homogeneous medium. In the grafting performed in heterogeneous medium, the reaction is carried out in aqueous medium using a suitable initiator. As initiator, the radiation or...

This study investigates the frequency-dependence of fluid flow in heterogeneous porous media using the theory of dynamic penneability and a finite-difference method. Given a penneability distribution, the dynamic penneability is applied locally to calculate the frequency-dependence of fluid flow at each local point. An iterative Alternating Direction Implicit finite-difference technique is appl...
