antoineSolver is a solver for the OpenFOAM library.

The solver is actively being developed and models the temperature- and pressure dependent unsteady advection and diffusion of humidity in a laminar or turbulent flow. When saturation is reached the phase transition (saturated steam -> liquid) is modeled and water is transported as fog / rain. antoineSolver is capable of simulating condensing humidity in complex geometries.

Following video shows the mixing of cool, dry air with warm air saturated with humidity in a fairly large geometry. The big pipe has a diameter of 2 meters.
