Abstract
High accuracy three-dimensional numerical simulations are performed in quarter five-spot geometry to analyse miscible displacements with gravity override. Using a vorticity formulation, the coupling between viscous and gravitational effects is studied. Its is found that an optimal level of interaction among the viscous and gravity-related vorticity components leads to an improvement in displacement efficiency.
