Izvleček
Prispevek obravnava obnašanje požara oz. dimnega oblaka na odprtem prostoru. Prispevek temelji na analizi vira požara ter širjenja dimnega oblaka v okolico. Za simulacijo je uporabljen računalniski program FDS (Fire Dynamics Simulator). Model računske dinamike fluidov uporablja metodo simulacije velikih vrtincev za računanje dinamike gibanja zgorevalnih ostankov v okolici.Vir pozara je postavljen v okolico nevarne zgradbe, v prispevku je predpostavljena okolica elektrarne Krsko. Prispevek prikazuje kratko ozadje modela FDS ter začetne in robne pogoje, uporabljene pri modelu. Predstavljena je analiza izhodnih podatkov in predstavljana kakovost rezultatov. Prispevek podaja tudi nekatere popravke modela FDS, ki imajo pomemben vpliv na rezultate.

Izvleček:
The basic aim of this paper is to research the relevant features of the control and management of an outdoor fire event and its influence on the safety of the surrounding area. The work is based on an analytical study of the fire's origin, its development and spread. A computer program called FDS (Fire Dynamic Simulator) is used in the work to simulate the fire's behaviour.A program based on the CFD (Computational Fluid Dynamic) model usingthe LES (Large Eddie Simulation) is used to calculate the fire's development and the spread of the combustion products in the environment. The fire's source is located in the vicinity of a hazardous plant, e.g., a power or chemical plant. The article presents the brief background of the FDS computer program and the initial and boundary conditions used in the mathematical model. The output data is discussed and the validity of the results is checked. The work also presents some corrections to the physical model used and its validation by experimental data, which influences the quality of results. The obtained results were discussed and compared with the Fire Safety Analysis report included in the Probabilistic Safety Assessment of the Krsko nuclear power plant.
