Hi,

I am simulating a batch mixing vessel, which is an unbaffled STR with magnetic rod stirrer at the base of the reactor. The system I am modelling consists of two immiscible phases, air & water, where I am using the transient VOF solver to track the deformation of the interface (see picture below).

I want to introduce a tracer which is miscible with the water phase to track the concentration and estimate mixing times in the tank, where the tracer will be injected on the free surface. I wanted to ask how do I set up such a simulation (i.e., what model do I need to select in ANSYS, what is the general methodology/strategy).

Also as this simulation will involve a deformed liquid surface rather than flat liquid surface (tracked using VOF) are there any other considerations I need to make. So far from surveying the literature mixing simulations have only been performed for flat-liquid surfaces (single phase, no VOF)
