TL;DR: In this article, a two-dimensional computational flow solver for simulation of two-way interactions between moving rigid bodies and two-fluid flows is presented, where the fluids are assumed to be incompressible and immiscible.

TL;DR: A fully Eulerian approach to capturing the interaction between two fluids and moving rigid structures by using the fictitious domain and volume-of-fluid methods, which significantly simplifies numerical resolution of the kinematics of rigid bodies of complex geometry and with six degrees of freedom is presented.

TL;DR: A piecewise-linear, volume-of-fluid method for reconstructing and advecting three-dimensional interfaces and contact lines formed by three materials, which preserves the accuracy and mass-conserving property of the Youngs method in volume-tracking three materials.

TL;DR: The feasibility of running MPI-parallel, GPU-accelerated, multiphase flow simulations on Amazon's Elastic Compute Cloud (EC2) service is evaluated as an alternative computational resource and Amazon's EC2 service is studied from an economic perspective and compared with a conventional local cluster.

TL;DR: In this article, the secondary droplets formed during the impingement of a train of ethanol drops were characterized using three-dimensional direct numerical simulations performed under conditions under which a train was impinguated.
