For more than 25 years, the in-house code Free Surface 3D (FS3D) has been developed at ITLR to investigate multi-phase flows with the aid of Direct Numerical Simulations (DNS). The code is based on the volume of fluid (VOF) method and solves the Navier-Stokes equations for incompressible flows. Additionally, the energy equation is solved, including the option of phase change such as evaporation or freezing. The simulations with FS3D focus mainly on the momentum, mass, and heat transfer processes across phase boundaries. The following research areas use FS3D for HPC simulations on Hawk: High-fogging in compressor cascades, multicomponent droplet impacts onto dry and wetted walls with and without structures, binary droplet as well as droplet-jet interaction, aerosol generation, droplet grouping phenomena, and single- and multicomponent droplet evaporation.
