Numerical modeling of underfloor heating system using CFD procedures with Elmer software

In the paper, the usage of multiphysical simulation software Elmer for simulating underfloor heating systems in a building is presented. Calculations were carried out in areas of solid elements of the model of the room, with the behavior of air and its temperature distribution was also taken into account. Results were compared with those obtained from other model based on a study of the temperature field only in solids, where the room’s temperature is known, or its change is given.
