Experimental studies were conducted in the PolyU/USTC Atrium to investigate the rise-time of buoyant plume front induced by pool fires. Through a series of full-scale burning tests, three semi-empirical equations were derived to predict the rise-time of buoyant plume front induced by a fire at three positions. These three positions are at the centre, near a wall and in the corner of the atrium floor respectively. The rise-time in dimensionless form and the plume radius equation are analyzed based on the measured data.
