  • The effect of spirality flow on heat transfer in limited lamilloy was researched by numerical simulation in rotation state. It is found that because of the side wall, the symmetric spirality flow was encased in the rotating limited lamilloy, which can restrain secondary flow produced by Coriolis force, contributing to the heat transfer in rotating limited lamilloy. The centrifugal force and Coriolis force have a significant impact on spirality flow. The impact field of spirality flow decreases with the increasing rotation speed. The heat transfer of rotating limited lamilloy can be increased by designing the length of rotating limited lamilloy reasonably.
