Numerical Simulation of Fire Thermal Radiation Field for Large Crude Oil Tank Exposed to Pool Fire

The radiant heat of the oil tank liquid combustion flame is the main reason of the fire spread between the oil tanks. In this paper,the thermal radiation characteristics of 10 million cubic meters oil tanks in Zhoushan Crude Oil Reserve Base in the pool fire environment are simulated using Fluent software.The results show that, the pool fire radiation intensity close to the ground was smaller than that in the parts over the tank mouth. The incident radiation intensity is over 200 kw/m 2 within the scope of radius 200m from the flame center. The incident radiation intensity decreased to 100 kw/m 2 in the place of 250m from the flame center radius. The radiant heat intensity was nearly 400-1000 kw/m 2 in the place of 72-152m from the flame center radius. The thermal radiation flux will lead to disastrous fire or explosion of the adjacent oil tanks.
