摘要
运用确定性混沌分析技术 ,研究了气液两相单孔鼓泡过程的混沌机理 .结果表明 ,单孔鼓泡过程是由周期及拟周期鼓泡通向混沌的 .鼓泡过程随气体流量增加可分为 3个动力学流区 :周期鼓泡区、混沌鼓泡区及喷射区 .
The chaotic bubbling mechanism in the gas-liquid two-phase bubble column with a single orifice was studied using the deterministic chaos analysis technique.It was found that when the values of gas flow rate was low,the stages of period icity and quasiperiodicity could be clearly identified.And when increasing gas flow rate,the sequence led to chaotic behavior.The bubbling process had three different flow regimes with the increase of gas flow rate:periodic bubbling regime,chaotic bubbling regime and jetting bubbling regime.
