• W3163366300 abstract "• Experimental data shows that under flow regime transitions the typical trend of phase distribution can change. • An experimental dataset on impact T-junctions for the refrigerants R32, R1234ze, R134a and R125 was made. • An extensive comparison of phase distribution models shows that they are not applicable to other working fluids as for which they are conceived. • A novel phase distribution algorithm is presented taking into account thermophysical fluid properties. • The new algorithm allows to predict phase distribution with a MDA of the phase mass fraction below 0.05 in 90% of the cases for different working fluids. Two-phase flows of refrigerants commonly occur in a multitude of systems in the power and process industries, including heat pumps, organic flash cycle,... These flows often have to pass through T-junctions to divide the inlet stream into two outlet streams. Herein, phase maldistribution can occur, meaning that the vapour qualities in the outlet are not equal to the inlet vapour quality. Undesired splitting could lead to unwanted effects, such as to much superheat after evaporation if less liquid phase entered the corresponding exit branch than was expected. Or liquid impact in turbines when to much liquid was allowed to flow to the turbine. Therefore, gaining insight into phase maldisdribution for refrigerants is important to be able to predict the amount of each phase in each exit branch. In literature, data is mostly available for air-water flows and models are built and validated solely on these datasets. The present work extends the air-water data of phase distribution over a horizontal impacting T-junction with data on different refrigerants. For this purpose an experimental setup was developed which can test refrigerant flows with mass flux G up to 700 kg.m − 2 . s − 1 at a saturation temperature between 10 ∘ C and 20 ∘ C and with a vapour quality x between 0 and 1. In total 551 experiments were performed with four different refrigerants: R32, R134a, R125 and R1234ze. For inlet superficial liquid velocities equal or higher than 0.2m/s it was found that with increasing inlet superficial vapour velocities, the amount of liquid phase flowing to the branch with the lowest mass flow rate decreased. This trend is consistent with literature. A discontinuity in this trend was observed when a flow regime transition occured. For the refrigerant R32 and an inlet superficial liquid velocity equal or lower than 0.1 m/s, the liquid phase followed an opposite trend by preferring the branch with the highest mass flow rate. The models from literature do not predict the refrigerant data with the necessary accuracy. They only work for specific refrigerants and for inlet flow regimes similar to the flow regimes of the air-water data used to construct the model. For this reason, the provided work also presents a new phase distribution model created upon the data gathered." @default.
