I have to admit that initially I have used VOF. However, since in the next step I wanted to introduce the dissolvation of O2 from the  gas phase into the lq phase (considering Henry's law), and since within the Mixture model this is possible via GUI (without UDF), I have considered that selecting the Mixture model is a better option.

Thank you very much for all your help, suggestions and hints! :)
