- •
Flow boiling of LN2 in a horizontal corrugated tube was experimentally studied.
- •
Helical corrugated structure improved fluid wetting, leading to unstratified flow.
- •
Nucleate boiling and convection dominated heat transfer were recognized.
- •
The effects of heat flux, vapor quality, inlet pressure, and mass flux were analyzed.
- •
Parametrization of the correlation including the two heat transfer modes were obtained.
