Calculation of pool fire thermal radiation safe distance based on Monte Carlo method

In order to study pool fire thermal radiation safe distance quantitatively,a pool fire thermal radiation propagation model was established,and Monte Carlo analysis was used to calculate the thermal radiation intensity from the storage tank.The model assumes that the parameters of liquid pool diameter,the ambient wind speed,temperature,relative humidity and the flame surface thermal radiation level were in keeping with some random distribution laws.The simulation results showed that the thermal radiation intensity in pool fire was line with logarithmic normal distribution,and the frequency of received radiation intensity of less than a certain threshold at target position increases with distance.
