Combined heat and mass transfer for laminar flow of moist air in a 3D rectangular duct: CFD simulation and validation with experimental data
TL;DR: In this paper, computational fluid dynamics simulations are performed for convective heat and mass transfer between water surface and humid air flowing in a horizontal 3D rectangular duct, where a hydrodynamically fully developed flow of moist air flows over the surface of a water tray, water evaporates from water tray to the air stream.
