The air and water flow distribution are experimentally studied for a round header - microchannel tube configuration. The number of tubes were 10 and 30. The effects of tube outlet direction, tube protrusion depth, mass flux, and quality are investigated. For the downward flow configuration, the water flow distribution is significantly affected by the tube protrusion depth. For flush-mounted configuration, most of the water flows at the frontal part of the header. As the protrusion depth increases, the water is forced to the rear part of the header. However, for the upward flow configuration, the effect of the protrusion depth is negligible. As the mass flux or the quality increases, the water flow is forced to the rear part of the header. Negligible difference on the water flow distribution is observed between the parallel flow and the reverse flow configuration.
