models available in the Fire Dynamics Simulator. A theoretical example was provided of a computeranalysis using experimental models of pyrolysis and sprinkler models. One of the mostimportant factors that affect results of building safety computer analysis if the heat release rate(HRR) obtained in the model. It may be defined in many ways in computer programmes. Usemay be made of the basic method, i.e. a defined value of HRR may be entered, independentlyof simulation conditions. A more advanced method comprises calculation of HRR from themodel by simulating pyrolysis processes. Selection of a method for modelling HRR also definespossibilities related to modelling effects of water suppression. Modelling fire suppression bywater must take into account three most important elements: moving of water droplets throughthe air, transporting the water along the solid surface, and predicting the decreasing of theburning rate. The basic method is to modify HRR curve. More advanced methods allow theuser to model decay phase depending on amount of water which reaches fire area.
