Numerical Simulation on Pressurization Air Supply of Anti-smoking Staircase

As a example,the pressurization air supply of anti-smoking staircase and its former room was simulated.It shows that the uniformity of pressurization air supply is not important,and the air flow calculated according Code for Fire Protection Design of High Buildings can meet the positive pressure requirements for anti-smoking staircase and its former room.It also provides a basis for pressurization fan selection.
