Simulation of deliquescence of a salt particle

schwaral · September 3, 2021, 06:54

Hello everyone,

I wonder how I could approach the problem of simulating the transition from a dry to a wet particle. For the beginning, only one salt particle would be enough. In future particle particle interactions should be investigated as well.

I am happy for every little bit of input. I would like to use ANSYS Fluent.

For particle-particle interactions you need to use DEM method. Fluent has no DEM method, it has DPM (discrete phase model) which is like particle tracking. You can use 3rd party DEM software with Fluent.

Or

You can perform your desired analysis perfectly with Cradle CFD. Because it DEM is embedded in Cradle (even without any flow, you can perform DEM analysis with it). Also you can use Spray, Humidity, Adhesion models with DEM in Cradle. There is many tutorials in software about them.
