The application of high order finite difference methods to the diffusion-convection equation
The one dimensional diffusion-convection equation that describes the miscible displacement process of resident fluid by an invading fluid in a porous medium is approximated numerically with high order finite difference methods using five adjacent space node points by the Crank - Nicolson …

A finite element analysis of dissolved oxygen drawdown and sulfate production in strip mine spoil dams due to pyritic chemical reaction
… A finite element analysis is used to solve the diffusion-convection equation assuming steady state conditions and no internal oxygen sources. Oxygen recharge along the free surface is permitted. The analysis is performed in three steps. Step one calculates the nodal piezometric heads and …

Nonequilibrium phase Behaviour and Mass Transfer of Alkane Solvents(s)-CO2-Heavy Oil Systems Under Reservoir Conditions
… to accurately quantify the preferential diffusion of each component in alkane solvent(s)- assisted recovery processes with consideration of natural convection induced by the heated and diluted heavy oil. The Peng-Robinson equation of state, heat transfer equation, and diffusion-convection …
