Sažetak
One of the aims of the presented investigation, carried out as a part of a PhD thesis, was to develop a reliable numerical model that can be used for assessments of thermal comfort in open – plan offices. The office under the investigation is air – conditioned by two parallel ceiling air terminal devices (ATDs). During simultaneous operation of the ATDs, an interaction of produced turbulent wall jets can occur, resulting in creation of complex airflow patterns within the occupied zone that influence on the achievable level of thermal comfort. A three – dimensional steady – state mathematical model of the fluid flow and heat transfer problem was solved using a commercial CFD software Fluent, based on the control volume method. The numerical results were compared to experimental measurements, carried out in a full – scale test room situated in the Laboratory of Heating, Ventilating and Air – Conditioning at the Faculty of Engineering University of Rijeka. The comparison confirmed the model as a promising tool for assessments of thermal comfort in similar rooms.
