Abstract
A visualization experimental study was conducted to investigate the phase distribution of two-phase slug flow in horizontal multi-parallel micro-channels, which was composed of a header with hydraulic diameter of 0.667mm and three parallel channels with hydraulic diameter of 0.500mm, all with rectangle cross section. Nitrogen and 0.03wt% sodium dodecyl sulfate (SDS) solution were used as the test working fluids. The inlet superficial velocities of gas and liquid varied from 0.130 to 1.47m/s and from 0.128 to 0.900m/s, respectively. The high speed recording technique was utilized to elucidate the fluid dynamics of two-phase flow in parallel micro-channels. It was found that the phase distribution characteristics of two-phase flow in parallel channels highly depended on the inlet gas slug length and the inlet real velocity, and the channels in the front of the header can influence the phase distribution of the adjacent channel in the rear. Moreover, a uniform phase distribution was achieved at high real velocity with short gas slugs.
