Abstract: Aviation kerosene uses jet fuel No.3 (JET A⁃1), which is a common source of danger in leaking fires.Based on theoretical analysis and PHAST software simulation, the influence of a tank leak in the aviation coal tank area on the surrounding storage tank was studied. The method for determining the safety distance between the tanks was introduced. The results show that the thermal radiation intensity increases with the increase of wind speed, and the thermal radiation value at the maximum wind speed increases by 65.7% compared with the average wind speed. As the distance increases, the radiation value becomes smaller, and as the height of the tank increases, the heat radiation value becomes larger, and the atmospheric humidity has less influence on the heat radiation. It is determined that the safety distance of the oil tank of the project is 17 m. The theoretical calculation is carried out by using MATLAB software and compared with the numerical simulation results. The maximum error is 18.7%, which has strong reliability. The research results have important theoretical and practical significance for tank tank design and guiding emergency disaster relief.

摘要： 航空煤油采用3号喷气燃料（JET A⁃1），其是泄漏火灾中常见的危险源。基于理论分析、PHAST软件模拟，研究了航煤罐区中一个储罐泄漏引发池火灾后对周边储罐的影响，介绍了储罐之间安全距离的确定方法。研究结果表明，热辐射强度随着风速的增大而增大，最大风速时的热辐射值相对于平均风速时的辐射值增加了65.7%；随着距离的增加，辐射值变小，且随着罐体高度的增加，热辐射值变大，而大气湿度对热辐射影响较小；确定了本工程油罐安全间距为17 m；采用MATLAB软件进行理论计算并与数值模拟计算结果进行对比，最大误差为18.7%，具有较强的可靠性。研究结果对于油罐区设计、指导紧急救灾具有重要理论价值和实践意义。
