LPG儲(chǔ)罐事故危險(xiǎn)特性動(dòng)態(tài)模擬評(píng)價(jià)方法及軟件開(kāi)發(fā)
摘要: 對(duì)LPG危險(xiǎn)特性、易發(fā)事故及其發(fā)生機(jī)理進(jìn)行全面系統(tǒng)地分析、歸納和分類,按LPG儲(chǔ)罐事故可能發(fā)生的先后順序,將其事故類型分為六類,建立了一套可描述事故特征參數(shù)隨時(shí)間和距離的變化過(guò)程的LPG儲(chǔ)罐事故危險(xiǎn)特性動(dòng)態(tài)模擬評(píng)價(jià)系統(tǒng)方法.為便于推廣和實(shí)際應(yīng)用,根據(jù)水平噴射火的特殊形狀,提出了其人員傷亡人數(shù)和直接財(cái)產(chǎn)損失計(jì)算方法;將改進(jìn)的噴射流擴(kuò)展半徑表達(dá)式用于噴射火模擬評(píng)價(jià),將修正的TNO爆炸特征曲線擬和關(guān)系式和蒸氣云爆炸人員傷亡距離關(guān)系式等改進(jìn)方法應(yīng)用于蒸氣云爆炸模擬評(píng)價(jià).結(jié)合Visual C++編程語(yǔ)言與MATLAB仿真技術(shù),實(shí)現(xiàn)了事故后果動(dòng)態(tài)模擬的軟件化、可視化.本方法對(duì)有效預(yù)測(cè)、預(yù)防、控制LPG危險(xiǎn)源事故具有重要工程應(yīng)用價(jià)值和指導(dǎo)意義. Abstract: The hazardous properties, easy occurrence accidents and accidents mechanics of LPG (liquefied petroleum gas) are analyzed and classified. According to occurrence precedence relation of LPG tank accidents, six accident types are classified. A method of dynamic simulation evaluation of LPG tank accidents hazardous characteristic is founded. A scientific practicable method of calculating casualties and property loss of horizontal jet fire is proposed; an improved expression of expand radius of jet is applied to simulate jet fire; some development methods of TNO Multi-Energy method in the engineering applications are also applied to evaluate VCE. Software of the evaluation method including dynamic visualization of accidents severity has been achieved combining program language Visual C++ and MATLAB emulation technique. The method has significant engineering application value and guidance function to take effective measures for forecasting and preventing accidents. 作 者: 陳國(guó)華 張瑞華 張暉 陳清光 顏偉文 Chen Guohua Zhang Ruihua Zhang Hui Chen Qingguang Yan Weiwen 作者單位: 陳國(guó)華,張瑞華,Chen Guohua,Zhang Ruihua(華南理工大學(xué)工業(yè)裝備與控制工程學(xué)院安全工程研究所,廣東,廣州,510640)張暉,陳清光,顏偉文,Zhang Hui,Chen Qingguang,Yan Weiwen(廣東省安全科學(xué)技術(shù)研究所,廣東,廣州,510620)
