水平管道中液塞长度波动的非线性分析The Nonlinear Analysis of Liquid Slug Length Fluctuation in Horizontal Pipe
赵庆军,何利民
摘要(Abstract)：
利用非线性分析技术中的分形理论在较宽的流速范围内对水平管空气 水段塞流中的液塞长度波动特性进行了研究。结果表明 ,水平管道段塞流的液塞长度符合对数正态分布 ,其波动是对初始条件敏感的混沌振荡 ,遵循分形统计规律 ,且具有持久性。通过对不同折算液速下的液塞长度波动特性的分析发现 ,液塞长度波动的混沌程度及波动对初始条件的依赖性在混合速度为 1 1m s左右时会出现极值
关键词(KeyWords)： 段塞流;液塞长度;分形;混沌;波动
