摘　　要：本文在对当前爆炸性气体环境的危险区域划分存在的主要问题及其原因分析的基础上,探讨了通过建立爆炸性气体环境危险区域计算机辅助划分平台,提高危险区域划分的可操作性,从而实现爆炸性气体环境危险区域划分方法的改善。探讨了通过运用数值计算方法,基于fluent对爆炸性气体扩散进行研究,对非对称分布场所的危险区域划分提供划分辅助。This article analyzes the main problems in the current methods for dividing the danger areas of explosive gas environments, and discusses the ways to improve the maneuverability of dividing methods for dividing the danger areas of explosive gas environments by means of building computer-aided dividing models. Based on numerical simulation with FLUENT Software, this article also discusses the spread process of explosive gas, and provides an assistant method for dividing the danger areas of asymmetrically distributed explosive gas environments.
