Numerical simulations of outdoor wind effects on smoke spreading along a corridor: Physical and sensitivity analysis

Abstract In this study, the effects of outdoor wind on smoke movements along a corridor were investigated using a CFD code: Fire Dynamics Simulator (FDS). Firstly, a comparison between experimental and numerical results was carried out by varying outdoor wind velocity from 0 to 12.12 m/s, and good agreement was found between the two. Secondly, from the numerical data, it was found that smoke stratification state in the corridor depends on Froude number (Fr) and it can be divided into three cases: stable buoyant stratification (Fr
