Phase Distribution Characteristics of Bubbly to Slug Flow Transition Region in a 10mm ID Vertical Round Pipe

Autor: Wangtao Xu, Qingche He, Tao Huang, Shuhua Ding, Meiyue Yan, Luteng Zhang, Liangming Pan

Publikováno v: Volume 15: Student Paper Competition.

As a common heat transfer structure, the vertical round pipe is widely used in nuclear energy systems. The phase distribution characteristics of two-phase flow in a vertical round pipe is an important issue. For two-phase flow, combined with the loca

Research on the Air-Water Flow Regime and Characteristics in Rectangular Channel

Autor: Liang-ming Pan, Qingche He, Wangtao Xu, Luteng Zhang, Meiyue Yan

Publikováno v: Volume 4: Student Paper Competition.

Two-phase Flow is widely involved in reactor design and is directly relevant to reactor safety. However, the flow regime in narrow rectangular channels still needs further study because it has a considerable difference from tube and bundle channels.
