摘要:
化工储罐火灾(类似于池火)时常发生,而现有的池火辐射热流模型对池火近场的辐射热流预测不够准确,原因是现有模型没有考虑火焰脉动的影响。本文基于池火火焰脉动的特征对火焰形状进行合理假设,以建立考虑火焰脉动的池火辐射热流预测模型,并与实验数据、点源辐射模型、Shokri-Beyler模型、Mudan-Croce模型和经典固体火焰辐射模型进行比较。结果表明,新模型更能够胜任池火近场的辐射热流的预测,并能给出辐射热流的波动范围。
Abstract:
Storage tank fires,similar as pool fires, often occurred in chemical industry and oil tank farm.However,the available thermal radiation models inadequately predict the radiant heat flux in the near field of pool fire, considering the effect of flame pulsation.A revised thermal radiation model,by assuming the flame shape based on the characteristics of flame pulsation.Compared with the experimental data,point source model,Shokri-Beyler model,Mudan-Croce model and classical solid flame radiation model,the proposed model was more competent for calculating the radiative heat flux field near pool fire and gave the standard deviation of the perdition.
