Simulation of Small Pool Fire
The analysis of the existing mathematical models shows that for the enhancement of the fire prediction quality the serious improvement of models for burning of liquids is neccessary. The empirical models for calculation of the liquid burning rates are valid for steady state regime and they dont allow receiving the value of burning rate at the unsteady period, which is very important for the modelling of the initial stage of the fire. Besides that, they dont take into account the influence enclosure geometry which sometimes can sufficiently change the burning rate. This work is devoted to the development and approvement of the mathematical model for calculation of pool fire burning rate based on the CFD modelling. For the approvement of the model the experiment with burning of methanol in a stainless tank with internal diameter 50,5 mm and 11 mm depth. New boundary condition at the liquid surface was proposed. The use of this boundary condition allows getting stable self-regulated flame. The comparison of the calculated burning rate with the experimental data shows satisfactory correspondence.
