A lagrangian-eulerian method for simulating electrospray deposition

Research output: Chapter in Book/Report/Conference proceedingConference contributionpeer-review


We present a coupled Eulerian-Lagrangian two-phase flow solver suitable for describing mass and charge transfer in charged droplets undergoing Coulomb fission driven by an external electric field. The Eulerian solver is based on the discontinuous Galerkin finite element method and is capable of accommodating arbitrarily complex configurations using unstructured meshes. We simultaneously model the e↵ect of transient electrical fields generated by charged particles deposited on a substrate and a co-flowing gas used to stabilize the spray. We will compare spray patterns obtained using this approach with laboratory-generated spray samples.
