How can I define "Heat Transfer in Fluids" for water that flows through an air domain and reaches a Wetted Wall in COMSOL Multiphysics for a 2D model?

Hi all, I hope everyone is doing well and is in good health. In the simulation it is needed to change the phase of water that flows through an air domain. So I used Laminar Flow and Level Set...
