1. Introduction
The number of high-rise or super high-rise buildings has been increasing rapidly in recent years. High-rise building fire is a crucial concern of fire safety engineering and has attracted more and more attention due to the large number of casualties, such as the notable Jingan fire in Shanghai on Nov. 15th, 2010, 58 persons were killed in the disaster. Statistics have shown that smoke is the most hazardous factor in fires [1,2] hence it is worthwhile studying its spread. The driving forces of smoke spread include thermal buoyancy, expansion, heat pressure (stack effect), wind effect, mechanical ventilation and so on. The outdoor wind velocity increases exponentially with increase of building height, which has significant influence on the fire smoke spread in high-rise building. Outdoor wind may blow into the fire room from open windows and carry a large amount of smoke into the corridor, which threats the safety evacuation process significantly. Therefore, it is necessary to study the smoke spread velocity in the corridor under the effect of outdoor wind.
