ABSTRAKT

In our study, with the help of a fire dynamic simulator (FDS), full-scale oil tank fires are simulated, and the horizontal and vertical heat flux distributions underneath the fuel surface were studied. The horizontal heat flux distribution always has a peak underneath the fuel surface, and the peak gradually shift s to the edge of the tank with increase in the height. The effect of the grid resolution and the number of solid angles (NSA) on the fire environment was discussed and an appropriate grid size and NSA were chosen.
