Diego Taglienti, Fabio Guglietta, Mauro Sbragaglia
Abstract
Droplet deformation at finite capillary numbers is accurately studied in shear flows via Immersed Boundary - Lattice Boltzmann (IB-LB) simulations. A reduced model is introduced to capture nonlinear effects in droplet deformation and orientation.
