Data points of structures of R1233zd(E) flowing in a horizontal circular minichannel at low, medium and high values of saturation pressure after condensation

Database present structures of two-phase flow of R1233zd(E) in 3 mm hrizontal channel after condensation test section. Two-phase flow is adaibatic. Database contains datapoints which provide information of reduced pressure (ratio of saturation pressure and critical pressure), quality and mass velocity. 4 two phase structures are distinguished: bubbly flow, slug flow, intermittent flow and annular flow. This dataset was created as a result of the implementation of research project UMO-2021/41/N/ST8/04421 funded by the National Science Centre.
