Two computational fluid dynamics (CFD) softwares are applied to analyze the flow and temperature fields. One is ANSYS/FLUENT, the other is Fire Dynamics Simulator (FDS). This thesis is separated into three parts. First, FLUENT and FDS are applied to compare with Ting-Ya Tsai’s measurements, which built an experimental field with underfloor air distribution system. Next, use both FLUENT and FDS to analyze flow field of the studio, including different adjustments of entrance condition. Then, experiments are carried out to measure the temperatures when the studio is being used and, finally, a comparison between simulation and experiment results is given. From the current result, FDS is more accurate then FLUENT when comparing with Ting-Ya Tsai’s research. According to the simulation results of the studio, it will have no obvious improvement if the catwalk is keeping to intact with air flow. After comparing the predictions and measurements in the studio, it is found that the boundary conditions match with the real situation.
