CFD modelling of moisture transport and condensation

A detailed numerical model for simultaneous investi gation of temperature, relative humidity and air velocities fields in a room is described in this pa per. First some experimental investigations in a fu ll scale cell are presented, and then a CFD model is u sed to simulate the experimental set-up. The comparison shows a good performance of the numerica l model. Finally the numerical model is enhanced to represent the vapour condensation on co ld surfaces.
