Effects of airflow rate and supply air temperature on the airflow pattern under active chilled beam system

Effects of airflow rate and supply air temperature on the airflow pattern for Active Chilled Beams (ACB) system are investigated in this paper. The air velocity for the air jet near the ceiling are tested and recorded under both isothermal and non-isothermal conditions. The self-similarity for the a...
