COMPUTATIONAL SIMULATION OF FIRE IN A HIGH-RISE BUILDING WITH A VOID SPACE : Study on the heat and smoke behavior in buildings with large space Part 2

Abstract

This paper presents the comparisons between the field experimental results of fire in a high-rise building with a void space and the computational results by a standard high-Reynolds number k-ε model. In conclusion, the computational air flows and temperatures in the void space are locally higher than the experimental results because the computational results by the k-ε model with Boussinesq approximation overestimate the highly-buoyancy flows. However the inflow rate into the space and the averaged temperature in the space agree with the measurements relatively.
