ABSTRACT

The main purpose of this study is examination of fire accuracy and the reliability of numerical simulations of a plume in corner walls in a view toward practical applications to the simulation of fire safety planning. Corner plumes are computed numerically using the standard ?-? model and results are compared with model experiments. Three fire source locations are considered: (a ) at, (b) close to, and (c) away from the corner. Dependence on divided mesh systems, the difference between compressible and incompressible flow solutions, and the sensitivity of the initial values of ? and ? on results are investigated. The simulation predicts successfully entrainment of the corner plume.
