was improved by using a special fitting, acting as distributor,
which was installed inside the header.
Thus, the available results for non-boiling gas–liquid flow in
micro-channels are not conclusive. Furthermore, important
information associated with flow pattern and heat transfer data
is still lacking. Consequently, the aim of this work is to explore heat
transfer results for different gas–liquid flow patterns in horizontal
micro-channels, an area needed to be clarified. In this paper, the
flow pattern behaviors obtained from flow visualization and the
heat transfer results are discussed.
