New convection correlations for cooled ceiling panels in room with mixed and stratified airflow

That study about the development of new convection correlations for rooms with cooled ceiling (CC) panels has two main objectives : - to develop convection correlations for the CC surfaces in rooms with only natural ventilation. - to quantify the influence of the high aspiration diffuser on convection at cooled ceiling surfaces as well as at other wall and floor surfaces. To reach those tow objectives, full-scale experiments were conducted in a test chamber with CC panels when :a) no air was supplied and air movement was created by buoyant forces onlyb) air was supplied by a high aspiration diffuser that creates large air mixing in the room.
