T形柱体气液两相涡街现象的研究

Study of Appearance of Gas-liquid Two-phase Vortex Street around T-shape Column

本文在50mm管内，分垂直上升和垂直下降两个方向，试验研究了气液两相混合物绕T形柱体流动，发生气液两相涡街的一些现象，分析了两种尺寸的T形柱体当气液两相混合物流过时，旋涡脱落的一些规律．

The aPpearance of gas-liquid two-phase vortex street around T-shape column was investigated by experiment. The vortex emission of gas-liquid two-phase now passing around each one of two T-shape column with tWo flow direction (vertically upward & vertically downward) in a tube (inner diameter 50 mm) were measured. The rusults show that the body occurs no steady gas-liquid two-phase vortex street for vertically upward flow, also the same one for vertically downward.
