Experimental study on fast quenching of cryogenic LN2 flow through interior micro-fin tube

Lei Wang et al.

Summary: A novel interior micro-fin tube concept is proposed for cryogenic quenching acceleration, which significantly reduces time cost in the quenching process according to experimental results. The micro-fin structure induces a radial velocity component within the annular vapor film, promoting interface fluctuation or tearing and facilitating earlier liquid-wall contact at higher wall temperature.

Experimental investigation on cryogenic chilldown performance under high-Reynolds number condition and using interior micro-fin structure

Lei Wang et al.

Summary: In this study, a high-pressure chilldown test platform was established to test two different tube structures under different Reynolds number conditions. The test results showed that the interior micro-fin tube performed excellently in improving chill-down rate, due to its induction of a radial velocity component in the inverse annular vapor film.

Experimental study on cryogenic chilldown performance through a thick-wall tube

Lei Wang et al.

Summary: In this study, the influence of tube wall thickness on chilldown characteristics was investigated through a high-pressure cryogenic chilldown test platform. The results showed that a thicker wall tube requires a longer chilldown time and larger liquid consumption, resulting in lower chilldown thermal efficiency.

Experiments and modeling on cryogenic quenching enhancement by the structured capillary-porous coatings of surface

I. P. Starodubtseva et al.

Summary: This study investigates the influence of structured capillary-porous coatings on cryogenic quenching process using both experiments and numerical simulations. The results show that the coating significantly affects the dynamics of quenching, reduces total quench time, and promotes earlier transition to nucleate boiling, resulting in a decrease in quenching time. The reliability of the results is confirmed through direct comparison with experimental data.
