The distribution of the gas phase in the bubble flow in the vertical assembly of 3×3 rods with gas injection from a single source

The work is devoted to an experimental study of the distribution of gas along the channel cross-section in the form of an assembly of vertical rods 3×3 in a square arrangement. The gas was introduced into the channel from the corner rod through a single capillary. Upstream, a local gas content senso...

Description
Summary:The work is devoted to an experimental study of the distribution of gas along the channel cross-section in the form of an assembly of vertical rods 3×3 in a square arrangement. The gas was introduced into the channel from the corner rod through a single capillary. Upstream, a local gas content sensor was attached to the the central fuel element simulator. The position of the sensor was changed by rotating the rod around its axis. The experiment was carried out at Reynolds numbers Re = 4500 - 9000 and flow rate gas contents of 2 - 4%.
