Modeling two-layer thin-film flows in a channel with applications to fluid displacement

Kamran Alba (University British Columbia)

Multi-layer thin-film flows in a confined geometry are largely observed in both nature and industry. In particular, displacement flow of one fluid by another is of interest that appears in many oil and gas processes such as well drilling, cementing and hydraulic fracturing. The fluids involved are often non-Newtonian. Weak inertial effects may also exist. Density differences often lead to stratification during displacement and potentially to instability/mixing. Here, a recent work on modelling these flows in a 2D channel is presented following a weighted residual approach. The model can capture the evolution of the interface between the layers as well as assessing its stability.
