Accurate and efficient boundary integral computations for interfacial flow with surfactant Siegel, Michael
We present accurate and efficient numerical methods to simulate the deformation of drops and bubbles in Stokes flow with surfactant. Both insoluble and soluble surfactant will be considered. For insoluble surfactant, a new boundary integral (BI) method is presented in which a special quadrature originally developed by Helsing and Ojala is used to retain accuracy for close drop-drop interactions (joint work with Sara Palsson and Anna-Karin Tornberg, KTH). For soluble surfactant, we describe longstanding work and recent results on the development of a hybrid or multiscale BI method that resolves a transition layer of bulk soluble surfactant near the interface (with Jacek Wrobel and Michael Booty, NJIT).
