Based on the investigation of gas flow, combustion and heat transfer in the converter, the authors introduce some distribution functions which control the generation of droplets. Monte-Carlo method was used to simulate randomly generated droplets(size, initial position and initial velocity). The droplet movement was calculated under the Langrangian framework. Heat exchange and temperature of droplets were calculated on its movement trace. Finaly, total droplet behavior were statistically described by some important physical parameters, such as,droplet average residence time in the gas, average maximum rising height as well as average amount of heat transfer from the gas to the metal bath.This model is characterized by the combination of probability statistics and differential equations to describe the behaviour of droplet, and it is believed to be very close to the actual problem described. It will also be beneficial for study other physical and chemical behavior of the droplet in the converter. As an example of using this model,the droplet behavior was researched in the 180 t BOF.(Correspondent: LI Baowei, associate professor, Baotou Universily of Iron and Steel Technology, Baotou014010) Key words： droplet    mathematical model    Monte-Carlo method      服务 把本文推荐给朋友 加入引用管理器 E-mail Alert RSS 作者相关文章 李保卫 贺友多 44.8K 链接本文: https://www.ams.org.cn/CN/      或      https://www.ams.org.cn/CN/Y1995/V31/I16/145 1HiraiM,TsujinoR,MukaiT,HaradaT,OmoriM．TransSteelInstJpn,1987;27:8052SugiyamaS,AbeM,NishiokaS,NakamuraH,TakahasiK,KawaiY．TransIronSteelInstJpn,1987:27:133MikrovasAC,ArgyropoulosSA,SommervilleID．IronmakingSteelmaking,1991,18:1694贺友多,SahaiY．金属学报,1992;28:B5235ShangLiuyi,OetersF．SteelRes,1991,62(3)．956GeorgeRS,PierreSt．AReportonthePost-combustionintheOhioStaleUniversity,November,19937李保卫,贺友多,SanaiY．包头钢铁学院学报,1994;13:48KoriaSS,LangeKW．MetallTrans,1984;15B:109$ [1] 侯玉柏, 于月光, 郭志猛.
