Abstract
In this paper, air and water is working fluids. Flooding phenomena and the characteristics of pressure drop in countercurrent gas-liquid two-phase flow in vertical narrow rectangular channels were investigated using 500mm and 1000mm test section length. The results indicate that the gas velocity required for flooding decreases as the test section length increases at the same liquid flow rate. Moreover, the vanishing and hysteresis of flooding becomes more apparently as the tube diameter length increases.
