| Abstract | In this paper, the effect of time varying fracture skin porosity on the contaminant transport mechanism in the fracturedporous media is analyzed using numerical modeling. An implicit finite difference numerical technique has been used to solve thecoupled non-linear governing equations. The effect of increasing porosity with time on the contaminant transport mechanism hasbeen analyzed for various initial fracture skin porosities. Results suggest that time varying fracture skin porosity can affect thecontaminant transport mechanism in a fracture matrix coupled system The concentration rapidly reduces within the fracture forvarious half fracture apertures and fracture-skin diffusion coefficients due to the effect of time varying fracture-skin porosity. |
