Topic
“An Efficient Surface-Based Numerical Method for Flow with Soluble Surfactant”
Speakers

Abstract:
We address a significant difficulty that occurs in computation of fluid interfaces with soluble surfactant in the limit of large bulk Peclet number. A transition layer develops adjacent to an interface where bulk surfactant concentration varies rapidly and this must be resolved accurately to evaluate surfactant exchange between the interface and bulk flow. A new "hybrid" numerical method is presented that incorporates a singular perturbation reduction of the transition layer into a surface-based solution of the interfacial flow problem. This is joint work with Michael Booty (NJIT) and Qiming Wang (University of British Columbia).
