✦ Synopsis

r an, China An experimental study of two phase boiling heat transfer of liquid nitrogen in a vertical lunate channel, which was formed by extreme eccentric circular tubes, was carried out and is reported. The experimental results show that the heat flux amounts to 9000 W/m2 while the temperature difference of heat transfer is only 1.1 K in lunate channel. The performance of heat transfer reaches the similar level as sintered tube with porous surface whose boiling heat transfer coefficient is admitted to be the highest at present.
