In the field of multiphase systems droplet-laden channel flow presents a challenging topic not only because of how turbulent flow influences the mass and heat transfer properties of droplets but also how droplets modulate the flow. In this contribution we focus on droplet-laden turbulent channel flow with phase transition generalizing earlier work by [1, 2] and introducing gravity in the wall-normal direction which acts both on the flow and on the droplets. Gravity leads to a mean motion of droplets towards the bottom wall where they accumulate and form a film of water.
