Abstract. A mathematical model called BUOYANT has previously been developed for the evaluation of dispersion positively buoyant plumes originating from major warehouse fires. The addresses variations cross-plume integrated properties (i.e., average along a trajectory) rising plume in vertically varying atmosphere and atmospheric after rise regime. We have described this article an extension to ...

Numerical studies on internal fire whirls (IFW) generated in a vertical shaft model with single corner gap were reported this paper. The generation of IFW, burning rate fuel and temperature studied experimentally first. simulations medium-scale IFW carried out using fully-coupled large eddy simulation incorporating subgrid scale turbulence source heat release rates compiled from experimental re...

fire is one of the most dangerous phenomena in the world which yields main damages, healthy and economical, and is thus a major threat to hospitals. since, most of the residents in hospitals are the individuals who cannot rescue themselves in such situations, fire in hospitals is more hazardous than any other public place; hence, it can endanger several sophisticated medical equipment. therefor...

This study is a preliminary research to specify fire scenarios in storage tanks and evaluate the size based on type of fuel diameter tank by applying liquid evaporation model FDS . version 6.7.6 was used analysis, computational domains were established pool with same proportion. The results obtained from indicated that heat feedback surface relatively well matched previous empirical correlation...
