Abstract: Spirally corrugated tubes are widely used as high-efficiency heat transfer tubes in various industrial production fields due to their simple manufacturing, low cost, and bidirectional enhanced heat transfer ability. In ...

Abstract: In this paper, the flow condensation heat transfer characteristics of the environmentally friendly nearly-azeotropic refrigerant R1234ze(E)/R152a (mass ratio of 40:60) in smooth tubes with varying structures were numerically ...

Abstract: R290 is considered to be an excellent alternative refrigerant for domestic air conditioners in the future. In this article, computational fluid dynamics (CFD) numerical simulation was used to obtain the flow field distribution ...
