摘要

1. A reliable system has been designed and constructed that employs the technique of Salt Water modeling to investigate the movement of smoke in structures. A series of experiments were conducted in a one-tenth scale model using the salt system. 2. FDS simulations were performed for a wide range of fire sizes in the full size compartment. 3. The scaling technique is sound and consistent. Good results have been seen in both the Salt Water system and the computer modeling program FDS. 4. Both systems show the same dimensionless time for the flow front to reach a point, indicating that for a given compartment configuration and known fire size, a good approximation could be made of the time for the smoke to reach a point of interest. 5. There is very good visual agreement between the salt system and the FDS simulations. 6. Both Salt Water modeling and FDS can be useful tools for visualizing smoke movement in structures. 7. The temperature history at a point of interest and the salt mass fraction at the analogous point have been scaled successfully using factors that absorb the source terms. 8. More work needs to be done with the scaling of the temperature and salt mass fraction in order to (a) compare the two systems and (b) use the systems to predict temperatures in fires. 9. Instrumented fire tests should be conducted and the results compared to both the salt water system results and the FDS simulations.
