I am evaluating options so thanks in advance for any recommendations. So I want advices or recommendations if you have experience with other software like Comsol, Open Foam, CFX for example, specially related to the learning process required to addapt to them, if the graphic interface is friendly user, etc. As you can see I have already tried everything in Fluent, that says to me that mass transfer models that Fluent offers do not addapt well to the default algorithm of calculation the software has, in fact if you read the theory guide it says Ranz Marshall, Hughmark models where formulated based on steady cases, multiphase flows are transient by nature. The system is a semi batch bubble column (11 cm diameter and 1.78 m of liquid height) with continuous circulation of gas (enters the domain at flow rate of 8.861 e^-5 kg/s). I did 35 attempts with divergence, before I verified that values for Henry volatility were correct and other material properties. Turbulence models I tried all k epsilon and k omega families.

The interfatial forces I considered where drag (grace) and lift (tomiyama). For outlet I tried: deggassing, pressure outlet and outflow. I tried 3 inlet boundaries: mass flow inlet, velocity inlet and pressure inlet. I tried the 3 options available to model mas transfer in Fluent: Ranz Marshall, Hughmark and entering a constant value of global mass transfer coefficient all cases diverged. I tried phase coupled and simple pressure velocity couplings with different Courant values (1,10 and 20) with adaptative timestep and also tried to decrease uder relaxation factors. Regardless of initial conditions, boundaries, discretizations schemes, mesh checking (min quality of 0.3) with sizes of 2 mm, 4mm and 2 cm, the case diverged after enabling species mass transfer, before enabling it I achieved convergence for the fluid flow equations at first stage of the simulation approach without any problem. I tried to simulate multiphase species mass transfer in a bubble column reactor for a O3-water system with the Eulerian two phase model, VOF and mixture model in Ansys.
