Fire smoke dispersion inside and outside of a warehouse building in moderate and strong wind conditions

A moderate-sized (8 MW) fire was modelled in a warehouse located an urban area with diverse architecture, wind conditions. The investigation includes the effects of neighbouring architecture on field, and consequence smoke control performance dispersion near-field building. Overall, 25 CFD simulations were performed ANSYS Fluent code, for velocities 5 m/s (moderate), 10 (strong) at 12 angles each (0°–330°, 30° increment), 0 reference. building venting system's affected by wind, reaching 74%–114% 78%–158% reference mass flow moderate strong velocities, respectively. Surprisingly, multiple cases exhaust rate ventilators increased, rather than hindered wind. We attribute this to arrangement inlets outlets façades resulting pressure difference between wall roof openings. plume highly dependent angle, type up- downwind fire.
