N2 - Heat exchangers with microchannels (hydraulic diameter less than 1mm) are attracting significant attention lately. Performance of these heat exchangers, evaporators mostly, are greatly affected by imperfect distribution of a two-phase fluid to each channel. This paper presents overview of the issue, shows basic option to evenly distribute single and two-phase fluid, and methods to determine maldistribution. Special attention is given to describing two-phase regimes in an adiabatic horizontal header with R134a as a fluid, describing a two-phase map with area of good distribution.
