1、2017年9月 第36卷第9期前瞻与综述Forward-looking&Overview文章编号:1000-8241(2017)09-0993-08气液两相混输管道水热力模型研究进展李岩松中国石油大学(北京)城市油气输配北京市重点实验室摘要:气液混输的本质是多相多组分非稳态流动、传热与传质耦合的复杂过程,在气液混输管道中,流体介质除了与管壁存在能量和动量的传递外,在两相相界面上亦存在动量、能量及质量的传递。通过总结气液两相流数学模型相关研究成果,分别从一维与高维、稳态与非稳态角度,分析了未充分考虑传热与传质影响的气液两相管流数学模型的研究现状和局限性,评述了考虑传
2、热和相变耦合影响下的气液两相流数学模型研究进展。最后指出,耦合传热和相变理论的相界面追踪、气液相界面复杂作用机理对传热传质的影响、复杂气液两相流型下的湍流模拟、气液两相平衡与非平衡相变机理以及开发用于求解气液两相流高维数学模型的快速高效算法,是该领域今后研究的关键问题和主要发展方向。(参58)关键词:气液两相管流;数学模型;传热;传质;进展中图分类号:TE832 文献标识码:Adoi:10.6047/j.issn.1000-8241.2017.09.002网络出版时间:2017-8-19:43:20网络出版地址:http://kns.cnki.net/kcm
