Novel dimensionless predictive flow pattern map for HFOs inside microscale enhanced tubes
Models designated to predict flow patterns in microscale geometries with enhanced surfaces such as micro-finned tubes are scarce in the literature and new low-GWP HFOs could benefit from the utilization of such geometries.

On the inclination effects during R515B vaporization inside a microfin tube
The impact of inclination on flow boiling inside a 7 mm outer diameter microfin tube is experimentally investigated and visualized for the low global warming refrigerant R515B. The heat transfer coefficient is evaluated at mass fluxes of 50, 100, 200, and 400 kg m–2 s–1, heat fluxes of 10, 30, and 50 kW m–2, at the saturation temperature of 30 °C, for ...
