Abstract
A Program Plume has been created to compute the air entrainment for a given fire size and a specified hot layer height. The solution is based on integration of conservation law equations. The empirical assumptions are related to the flame height and to the coefficient of entrainment and are based on the experimental data of California's Institute of Technology. Calculations are compared with the experimental results obtained in the field tests. The program seems to describe the experimental data better than other known methods. A software package called “Firecalc” includes seven modules, based on the plume model, which describe hot layer properties in confined compartments relevant to practical situations. The computational results of these modules are also in good agreement with available results of field and laboratory tests.
