Research on the thermal response behavior of double-layer oil storage tank in fire

Abstract

Abstract: Fluent is used to simulate the behavior of the double-layer-tank exposed to the pool fire of its adjacent tank. It is found that the temperature rise of double-layer-tank is 20% less than that of the single- layer- tank in 300 seconds of radiation.And the pressure rise of double-layer-tank is 15% less than that of the single- layer- tank. The evaporation rate of liquid hexane in double- layer- tank is much lower than that of single- layer tank. Double- layer- tank can effectively prevent wall damage caused by radiation, slow down the evaporation rate of light oil and reduces the VOCs emission under the pool fire accidents.This will significantly reduce the probability of secondary fire and explosion accident.

Key words: double- layer- tank, pool fire, numerical simulation, Fluent, temperature, pressure
