| 摘 要： | 应用伯努利原理和CFD应用软件FLUENT,对影响北方民居通风排烟和CO中毒事件的气象因子进行分析和数值模拟,研究基于气象条件的CO中毒事件预警方法。结果表明:影响民居通风排烟的气象条件主要有风速、气温(室内外温度差)、变压和相对湿度等。其中风速是影响通风排烟和CO中毒的主要气象因素;在弱风条件下,室内外温度差和气压的变化对通风排烟也有重要影响。在上述工作基础上,建立了民居通风排烟气象指数的计算方法和基于气象条件的CO中毒事件预警方法,经检验该方法对中毒事件有一定的预警能力。

| Abstract: | Based on the Bernoulli principle and computational fluid dynamics(FLUENT)software,the meteorological factors influencing ventilation,smoke emission of vernacular dwelling and leading to carbon monoxide poisoning accident were analyzed in the north areas of China,and numerical simulation was employed in order to discuss the early warning method of carbon monoxide poisoning accident in terms of meteorological factors.The results indicate that the main meteorological conditions influencing ventilation and smok... |
