The flow boiling pressure drops of three types of refrigerants were measured.
A single-phase flow validation was performed.
The impacts of operating conditions on pressure drops were examined.
A new two-phase frictional pressure drop model was proposed for high mass fluxes.
The new pressure drop model predict the data with an MAE of 27.8%.
