Two-phase distribution issues in microchannel HXs.

Author(s) : HRNJAK P. S. P.

Summary

Heat exchangers with microchannels (here meaning hydraulic diameter less than 1 mm) are attracting significant attention lately. The performance of these heat exchangers when used as evaporators or multipass condensers is greatly affected by imperfect distribution of a two-phase fluid to each channel. This paper presents an overview of the issue, showing basic options to evenly distribute single and two-phase fluid and the methods to determine maldistribution. Special attention is given to describe two-phase regimes in an adiabatic horizontal header with R134a as a fluid, describing a two-phase map with area of good distribution.
