The coupling in transient regime between the modelings of thermal and mass transfers inside a heated room and its radiator

In the present study, a simultaneous modelling, in transient regime and 3D, of the thermal and mass transfers inside a room of habitat (including its internal walls), heated by a hot water radiator, and the thermal and mass transfers inside the heating equipment is carried out. The adopted CFD code, at numerical simulations, is on a macroscopic scale. Comparing numerical values to the experimental quantities showed that the results of the used numerical code are satisfactory.
