Abstract

The liquid holdup distributions of four kinds of TH-VST with different angles and one kind of RH-VST with the same structure parameters are experimentally studied with the air-water system in the 1 500 mm×400 mm quadrate column. The experimental results show that the non-uniform degree of the TH-VST have better performance than that of RH-VST. At the same condition the non-uniform degree decreased and then increased with the increase of the angle of Trapezoidal hole and F_o-factor. It increased with the liquid weir load. Based on the experimental data, the angle range of Trapezoidal hole which have good flow distribution performance was determined. The correlative equation was obtained for the non-uniform degree, the result can be applied in the engineering design.
