本研究初步驗證火災模擬器火焰的可控制性與實驗過程的安全性，並確定此FDS可用於火災模擬器下的火災模擬，對於往後進步一的研究下，可依FDS先行模擬之結果來判斷實驗中可能遇到的困難及危害性，進而加以預防提高實驗之成功率與準確性。 The occurrence of fire has always caused a great calamity to mankind. How to carry on the rescue in the fire scene, reduce the injury when the fire occurs, resist expansion of the scene of fire and prevent the occurrence of the fire, etc, are the key subjects that people concentrate for a long time. In this thesis, we use Computational Fluid Dynamic (CFD) software: Fire Dynamics Simulator (FDS) program to simulate the discussion, solving the numerical solution in Navier-Stokes equation. FDS can be used for establishing the conditions similar to fire scene and shows the situation of dynamic simulation. In this thesis, we regarded propane gas as single gas, and measure with three different kinds of gas exporting type and fire source places. In the course of burning simulation of three kinds of different scenes, we are going to discuss following parameters, such as gas composition, thickness, temperature and speed in the combustion furnace and verify the simulation and experiment. The result of simulation shows that the place which putting fire source could influence the diffusion situation of temperature in the space. We also found that the vortices created because of the rising of the hot air collide to the barrier and ceiling or exchange of cold and hot air. From the results of experiment and simulation, we found the average temperature difference were about 11℃ or 11.7% which measured in V-gutter flameholder, 9℃or 8.03% in gas burner and 26℃ or 8.9% in storage fire simulator. The result in simulation is consistence with experiment. This thesis verified the control of flameholder of fire simulator and safety of experiment process at first and confirmed that the FDS software could simulate the fire in fire simulator. We can use the FDS software to simulate the fire before experiment to increase the accuracy of experiment and reduce the cost of experiment.
