Smoke Movement and Evacuation Time in the Arcade of a Traditional Market using Numerical Simulation

This study proposes to analyze the smoke exhausting performance and evacuation time in an arcade of a Korean traditional market. The effect of three types of ventilation opening on smoke exhausting performance was analyzed using the CFD (Computational Fluid Dynamics) method. The ventilation opening delayed the spread of smoke efficiently, and is an important design factor to control smoke movement in arcades. Also the evacuation time was analyzed according to the height of the building and increased significantly with the increase in the number of floors. Given the conditions of the study, the arcade building had to be less than three-stories considering the spread of smoke.
