Description

The purpose of this study is to examine the accuracy and reliability of the numerical simulation of plumes in corner walls from the view point of practical use of simulation for fire safety planning. Plumes in corner walls are numerically simulated with the standard κ-ε model and the results are compared with the basic experiments conducted by three positions of fire sources, (a) adjacent to the corner, (b) close to the comer and (c) apart from the corner. The dependence on mesh dividing system, the differences between incompressible and compressible model and the sensibility in results with the differences of initial κ, ε values are examined. The entrainment of plumes in corner walls is able to be practically predicted through the simulation.
