Description
Summary:博士 === 國立雲林科技大學 === 工程科技研究所博士班 === 95 === The major objective of this study was determine the accuracy in a large indoor stadium by FDS. In 2000, NIST/BFRL(National Institute of Standards and Technology/Building and Fire Research Laboratory) developed a CFD(Computational Fluid Dynamic) code – FDS(Fire Dynamics Simulator). It has become the most popular fire simulation software used by fire researchers in the world. Nevertheless, the result varies as the users choose different grid setting as grid size on fire source and aspect ratio. The accuracy and limitations of axi-symmetric fire plumes by numerical simulation were described by Ma and Quintiere. Using the characteristic length as the scaling factor, it is found that the optimum resolution of pool fire simulation is around 0.05. But it is difficult to make R* to 0.05 in a large indoor stadium. This study tries to find out the difference and limitations by means of case study to set up a basis for future researchers.
