A moving mesh method for non-isothermal multiphase flows
In this thesis, a numerical method is developed for simulating non-isothermal multiphase flows, which are important in many technical applications such as crystal growth and welding. The method is based on the arbitrary Lagrangian Eulerian method of Li (2013). The interface is represented …

Computation of the rise or fall of a drop through a suspending liquid with no mass transfer: Axisymmetric, transitional and complex regimes
… can lead to spurious velocities. Here, we use an Arbitrary Lagrangian-Eulerian (ALE) moving-mesh approach to investigate this using four test problems for which analytic solutions are available. An interface-fitted technique based on a stabilized Galerkin finite-element method is applied to the …
