초록
The fact that the major cases of life casualties are from smoke in the fire accidents and the expected steep increase of skyscrapers, huge spaces, multiplexes and huge scaled underground spaces demand establishment of efficient smoke countermeasure. In pressure differential systems for smoke management, the speed of airflow through open door between accommodation and lobby should be maintained over 0.5m/s on the whole area of door to prevent smoke from infiltrate into evacuation root when the door is open for refuge. The numerical analysis on features of airflow through open door are carried out and the results are presented.
