Development of Simulation System for Hear Radiation of Tank Fire based on Monte Carlo Method

Abstract

Estimation of the heat radiation from tank fire is important for the safety and reliability of chemical and oil plants, however, it is very difficult to estimate the heat effects because of complex phenomena such as wind conditions, the location and the shape of tanks, etc. In this study, we have developed a simulation system to clarify the effects of tank fire based on Monte Carlo method. In the evaluation of the heat, there are various parameters such as the tank diameter, height, wind velocity, distance from the tank, and so on. We proposed the development of the database of the heat radiation by using three parameters of 'wind velocity', 'Height / Diameter of a tank', and 'Distance from a tank / Diameter'. Furthermore, the simulation system for heat radiation from tank fire under the wind condition has been developed based on Monte Carlo method, the database and GUI（ Graphic User Interface）. From the numerical examples, the dangerous area for a human body can be estimated conveniently, and the proposed system is effective for the defense activity plan These results indicates that the proposed system can be applied for the safety and reliability of plants.
