A MAGNITUDE ORDER ESTIMATION METHOD FOR FORECASTING CONCENTRATION
室内泄漏燃气浓度分布的一个量级估算方法

In this paper, by analyzing the order of magnitude, the flow process of the leaking LPG is simplified into three independent sub-processes, including the process of LPG sedimentation to floor; spreading to other room and diffusing to roof, then a simplified method for forecasting concentration distribution of indoor explosion gas is put forward. The feasibility and simplicity of this method are discussed by applying it to analyzing an actual LPG explosion hazard.
