Microfin tubes are widely used to enhance heat transfer in heat exchangers in order to
reduce volumes, costs and refrigerant charge. Much experimental work has been published …

The flow condensation of R1234ze (E), R450A, and R515B was conducted in a 6.14 mm
inner diameter micro-fin tube. The fin height is 0.18 mm and the fin number is 50. The helix …

An experimental investigation was performed to evaluate convective condensation and
evaporation of R22, R32 and R410A inside a smooth tube (inner diameter 11.43 mm), a …

An experimental investigation was performed for convective vaporization of R22 and R410A
inside one smooth tube and five micro-fin tubes with the same outer diameter of 5mm. Data …

The design of micro-finned tube heat exchangers is a complex task due to intricate
geometry, heat transfer goals, material selection, and manufacturing challenges. Nowadays …

An experimental investigation was performed to evaluate the condensation heat transfer
characteristics for R32 and R410A inside four horizontal round tubes with 12.7 mm outer …

This work aims at estimating the efficiency gain resulting from using lean premixed
combustors in hydrogen-fired combined cycles with respect to diffusive flame combustors …

Condensation heat transfer of R1234yf inside smooth and microfin tube with 2.5 mm outer
diameter are studied experimentally. The experiments are carried out at a saturation …

This work proposes a new general and simple model to determine the local flow
condensation heat transfer coefficient inside plain pipes. The model considers two regimes …

The paper reports the experimental study of ammonia condensation in aluminium annuli
