Abstract
Three-dimensional numerical simulations have been performed to investigate the onset of oscillatory Marangoni convection in liquid bridges made of a high-Prandtl number fluid (Shin-Etsu 5 cSt silicone oil) using the OpenFoam computational platform and high- resolution structured grids. Different aspect (length to diameter) ratios and volume ratios have been considered corresponding to tall and shallow fluid zones with straight, concave or convex surfaces (microgravity conditions). Particles dispersed in the fluid have been tracked in the framework of a Lagrangian approach relying on the solution of the so-called Maxey-Riley equation. Both one- way and two-way fluid-particle coupling has been implemented. A set of data is presented with the express intent of supporting the optimization of a dedicated series of experiments planned for execution onboard the International Space Station (JEREMI Project).
