Visual study of flow patterns during evaporation and condensation of R-600a inside horizontal smooth and helically dimpled tubes

•Dimples in both evaporation and condensation influence the flow patterns.•Intermittent and annular flows were dominant flow pattern for the dimpled tube.•There was no stratified-wavy flow in the flow pattern map of the dimpled tube.•Transition lines of both dimpled and plain tubes were recognized a...
