- Abstract
- In relation to the experimental data by Steckler et al. on flows induced by a fire in a compartment, numerical analysis has been made using a three-dimensional differential field mode. The comparison of numerical results with experimental data indicates that the numerical solutions can predict mass flow rates within 35% discrepancy. Some factors, e.g. effects of the net released heat, radiative heat, local turbulent viscosity and heat source dimensions causing the discrepancy, are discussed. Accuracy will become much better by taking these factors into account in calculations. A nondimensional equation of mass flow rate is described.
