利用1∶1的水力学模型对双侧孔水口下CSP结晶器内部流场流动进行了瞬态研究.结果表明,液面波动具有明显的周期性加剧现象,称之为“液面动态失稳”.讨论了不同工艺参数下液面动态失稳的规律,用示踪实验法研究了流场内部的流动特征,分析了“液面动态失稳”与内部流场运动关系.液面的动态失稳现象主要是结晶器内的湍动能由下而上聚集并迅速耗散引起.
A 1: 1 hydraulics model was used to simulate the flow field inside the CSP crystallizer under the double orifice, and the results showed that the fluctuation of the liquid surface had obvious periodic exacerbation, which was called as " The law of liquid surface instability under different process parameters is discussed, the flow characteristics inside the flow field are studied by the tracer experiment method, and the relationship between the dynamic instability of liquid surface and the internal flow field is analyzed. The dynamic instability of the liquid surface is mainly caused by the turbulent kinetic energy in the crystallizer aggregating from the bottom up and rapidly dissipating.
