ABSTRACT

In this paper a traditional two-zone approach is utilised to examine three types of oscillations in temperatures of small-scale compartment fires, plus three types of nonoscillating fires. The formulation of the model is algebraic using a minimalist amount of computer resource and a simple program PARAFFIN has been described to perform the calculations. Limited data from literature supports the modelling and the dependence of oscillation frequency upon ventilation seems to be correctly recreated.

Keywords: Fire dynamics, Flashover, Oscillations, Ventilation.
