Suitability of R404A Boiling Heat Transfer Correlations for 5 mm Microfin Tube

Zhileng xuebao, 2020
The flow boiling heat transfer of R404A in a 5 mm micro-fin tube was studied. A number of flow boiling heat transfer models were selected by comparing the deviation between experimental results and theoretical calculations through a large amount of data ...

Numerical Investigation of Thermo-Flow Characteristics of Tubes with Transverse Micro-Fins

Energies
The article presents the results of numerical studies of heat transfer and pressure drops in a channel with transverse micro-fins. The main aim of the study was to prepare the thermal and flow characteristics of such a channel for a variable longitudinal spacing of micro-fins.
