In the following study COMSOL Multiphysics® was used to simulate evaporation of water droplets in a stream of heated air. This was a precursor to the modeling of a humidifier, which is used to humidify the air supplied to fuel cell stack. Since the percentage of water droplets was relative low, particle tracing method was used for the simulation. Motion of water droplets in a heated air stream, across a straight channel along with evaporation was modeled and the motion of generated water vapor was tracked. Generated water vapor eventually converged to a parabolic profile as expected for a laminar flow through channel.
