摘要
以水－空气两相流体为工质，研究了垂直向上两相流体横向冲刷准三角柱时的涡街特性及涡街结构．试验段管子内直径为５０ｍｍ，水流量为２５．８～１４ｍ３／ｈ，截面含气率为０．０２～０．３０．得出了两相流体中涡街频率、水流量、截面含气率三者之间的关系．
In this paper vortex street structure was studied in an air water two phase flow passing across a triangular prism. The tested tube inner diameter is 50 mm, the water velocity is 1 98～3 65 m/s, the void fraction is 0 02～0 30. Relationship among the vortex street frequency, water flow rate and void fraction was established. The vortex street structure in wake was also detected.
