Abstract: Indoor smoke movement is a very important issue in a building fire. It is related to the design of various fire protection systems, especially smoke control system. In the present study, a small scale compartment was developed to study the smoke movement with different smoke extraction design, for example, various smoking source heights and different fans locations. The results of the small scaled experiment were compared with the simulation results of the fire dynamics simulator (FDS). FDS, which is developed by the National Institute of Standards and Technology (NIST), is one of the computational fluid dynamics (CFD) models for fire-driven fluid flow and have been widely used in fire simulation. The software solves numerically form of the Navier-Stokes equations, applying for low-speed, thermally-driven flow, especially on smoke and heat transport from fires. The latest version FDS 5.5.3 was released in Nov 2010. As the innovative technology in fire engineering, FDS5 is extensively spread among researchers and engineers. From the present study, it is discovered that the FDS simulation results have a good agreement with small scaled experimental data in terms of smoke movement. However, the FDS could not provide a good prediction in temperature field.
