Bubble rising in ionic liquid CFD Simulation
NoAI: This model, simulation, images, or project may not be utilized within datasets, during the developmental process, or as inputs for generative AI programs.
Direct numerical simulation of 3 mm single bubble rising in (bmimbf4 Ionic) liquid performed with OpenFOAM. InterFoam solver is used to compute the two phase flow in the column. Grid size of 32 cells per bubble diameter per dimension and a time step of 0.00001s has been used. OpenFOAM Simulation files are also attached for download.

Hello Sir/madam,
I want to simulate Evaporation of a Water droplet.can you plz guide me in the creation of geometry and few settings in Fluent?

Hi, I never simulated evaporation in Fluent however I can try. Have you tried something already? I would suggest that you create/upload a new project here on FetchCFD and share the link so that I can have a look. I would suggest the following: try first 2D geometry/domain like square or rectangle column with mesh fine enough (e.g. a couple of hundred elements inside the droplet diameter) and small time step like 1e-5 or even smaller it should work. For boundary condition use wall on bottom as well as both sides and pressure-outlet or outlet-vent on top. Apply zero flux on side walls and temperature BC on the bottom. Under models select Volume of Fluid (VOF) as multiphase model and also switch on the energy equation. For materials select air, water (liquid) and water(vapor). Switch on species transport with water vapor and air as the components. Under phase panel select mass transfer and surface tension. In your case mass transfer will be from water to air so select mass transfer from water to air with water vapor as the migrating species and choose "evaporation/condensation as the mass transfer mechanism". Keep the condensation frequency as default and set boiling frequency = 1.0. Patch the water droplet with an initial diameter and volume fraction of 1. For patching and general idea have a look at this fluent simulation: http://fetchcfd.com/view-project/91
