Axial void distribution in two laterally interconnected channels with blockages

In this research the axial void fraction distribution in two laterally interconnected channels with plate or smooth blockages in one of them has been determined experimentally for different void conditions at the inlet of the blocked and unblocked channels. It is observed that a substantial recirculation zone with high void content forms downstream of the blockage. Outside of this recirculation zone, the void fraction in the unblocked channel is somewhat higher than in the blocked channel. The presence of the blockage promotes mixing between the channels, thus reducing the void differences that may exist between them. (author)
