Fire and Smoke Modelling

Fire smoke dispersion inside and outside of a warehouse building in moderate and strong wind conditions

“…Wind can affect the fire and smoke propagation in numerous ways. A wide range of approaches and models used in the prediction of outdoor pollutants is given in [11]. A review of global testing methodologies related to the vulnerabilities of buildings from large outdoor in the built environment is presented in recent ISO/TR 24188:2022 [16].…”

“…In recent review [11] different approaches to smoke modelling are identified, with CFD being proposed as a tool for near-field modelling (as in the current paper).…”

“…25 CFD simulations using commercial code ANSYS Fluent in version R19.2 were performed. In this Chapter we present the main assumptions for the numerical modelling, while details of used submodels, schemes and approaches may be found in review papers [49] and [11]. The details of the numerical schemes of ANSYS Fluent used herein can be found in its technical documentation [50].…”

“…A validation experiments for RANS simulations were performed by Nozu and Tamura [42]. More studies related to the modelling fires in environment can be found in [2] and [11]. The cited studies show that urban-scale modelling of the consequences of pollutant release is feasible.…”

“…This area is limited to the building's neighbourhood, at a distance up to 6 times the height of the tallest building in this region. Approach used in here for modelling the near-field may not be applicable to the assessment of the far-field, in which other than CFD types of models may provide accurate results at considerably reduced computational cost [11]. We also recognize that other approaches may be feasible for smoke spread analyses at different scales [11], however the scope of this work is limited to only CFD (with use of ANSYS Fluent) and the near field.…”
