A zonal model of compartment fire was developed to predict the heat flux distribution inside the room of origin. The feature of this model is expressed ; the room interior wall is divided into elements and the net heat flux of each part is estimated by means of net radiation method, in which the radiative interaction of heat between walls smoke and flame is considered.
In order to examine the validity and limitation of the proposed zone model, a series of experiments were conducted with a small scale model compartment under 32 different conditions consisting of several kinds of fire sources and ventilation openings. The macroscopic values of average heat flux, hot layer temperature and hot layer depth etc, and net heat flux distributions were in good agreement between the experiment and the prediction.
