- Abstract
- This report contains CFD-simulations of a tunnel fire in a scaled down road tunnel, 1:8, with the CFD-code FDS. FDS and its different sub models are evaluated by different configurations of grid nets, the radiation model and slight changes in the material database and the results with respect to temperature and u-velocity are compared to each other. Comparisons of the gain and loss in time by using the different configurations are also presented in the report. The aim of the report is to make a sensitivity analysis of FDS and its sub models and to find out how to make a resonable FDS-simulation of a tunnel fire without spending too many wall-clock hours on it.
