If the particles for smoke detection, fire alarm ahead of time, early fire-fighting and evacuation operations, you can reduce the disaster, disaster, the loss tends to the minimum, so very early fire detection will be born out. In this study, using computational fluid dynamics(CFD), based on fire dynamics simulation software (FDS) assist Aspiration smoke detector (ASD) design of large high-ceilinged space with actual experimental data analysis, mutual authentication to provide more solutions for fire safety design. FDS is a tool to simulate two smoke source, smoke particles and oil; smoke particles, the purpose of acceptance testing, in accordance with the FIA testing standards and simulation of slow growth fire; oil to explore stratification effect.The simulation of fast-growing line of fire. And then simulated three kinds of air flow field wind speed.The study found that in the FDS simulation ASD design, simulation results and the actual time data close to actual experimental data but results approximate the actual data tends to be idealistic.If you use of FDS data simulation ASD system design, reference for analog data need to set aside a certain amount of flexibility.
