Simulation on Annular Flow of R1234ze(E) Flow Boiling in Micro-tubes

Zhileng xuebao, 2020
A theoretical model for annular flow of R1234ze(E) flow boiling in micro-tubes was proposed in this paper. The surface coefficient of heat transfer and pressure drop were calculated using the model. The variation in the liquid film thickness profile due to the gravitational effect, surface tension, and liquid-vapor interfacial stress was considered ...

Comparative assessment of condensation and pool boiling heat transfer on horizontal plain single tubes for R1234ze(E), R1234ze(Z), and R1233zd(E)

Comparative assessment of condensation and pool boiling heat transfer on horizontal plain single tubes for R1234ze(E), R1234ze(Z), and R1233zd(E)
The low-global warming potential (GWP) refrigerant of R1234ze(E) is considered to be a prospective alternative to conventional R134a for car air conditioners, whereas the isomer R1234ze(Z) and R1233zd(E) are anticipated to be the low-GWP alternatives to R245fa used in high-temperature heat pumps and organic Rankine cycles.
