海洋平台池火火灾模型概述

An Overview of Pool Fire Models Applicable to Offshore Platforms

流行的建筑火灾模型多适用于描述着火过程、着火房间温度和烟气在建筑物内的流动,不能完全满足海洋平台火灾的研究需要。文章简述了建筑火灾领域中比较流行的半经验模型、场模型等,着重介绍适用于海洋平台特殊生产条件下的池火火灾模型。通过综合分析、比较现有的火灾模拟方法,回顾了国外成熟的半经验公式,分析了不同模型的适用性,得到适用于海洋平台池火火灾特性的计算方法。

Current fire models are mostly concerning combustion process,room temperature and smoke spread.Since there are distinct differences between offshore and onshore environments,those fire models are no longer completely applicable to offshore platforms.In this paper,general characteristics of those common fire models are reviewed,including semi-empirical models,field model,etc.and the pool fire model suitable for offshore platform production conditions is emphatically introduced.By means of comprehensive analysis and comparison of the current fire simulation methods as well as review of the foreign mature semi-empirical formulas and their applicability,the calculation method suitable for pool fire of offshore platform is obtained.
