Abstract: Smoke control design by using air curtains in spaces adjacent to `open-design' atria was evaluated using Computational Fluid Dynamics (CFD). The design mechanical installs systems for discharging air vertically downward (commonly known as an air curtain) to isolate spaces adjacent to the atrium for preventing smoke spreading to those areas. Performance of the design was evaluated by carrying out two sets of CFD simulations with heat release rates of the fire of 1 MW and 5 MW. An atrium of length 10 m, width 10 m and height 10 m with an adjacent area 6 m above the atrium floor was considered. Air speed of 1 ms-1 to 10 ms-1 discharged vertically downward, corresponding to volumetric flow rates of thirty-six air changes per hour to 360 air changes per hour of atrium volume space were studied.
