本文从非恒定、可压缩分层流基本方程出发,应用线性稳定理论,导出了非恒定、可压缩的分层流向塞状流转捩的判别公式。

An Investigation in the Transition from Stratified Flow to Slug One during Transient

According to the unsteady and compressible stratifed flow equations, the judge condition for transition from the unsteady and compressible stratified flow to slug one has been derived in this paper by using the linear stability theory. The numercal results and analysis show that gas and liguid flow fields in pipeline have a great influence on the judge condition. The possibility of the liguid state transition increases with the decrease of void fraction, and un der the condition of unsteady flow and steady one, the liquid state transition makes great difference.
