Heat transfer characteristics in condition of different angles between lamilloy and rotation axis in limited lamilloy under rotating state was researched by numerical simulation. The relation between lamilloy heat transfer capacity and angle between lamilloy and rotation axis was acquired. Results show that surface heat transfer coefficients present similar characteristic with different angles between lamilloy and rotation axis. The surface heat transfer coefficient is highest and the effect of buoyancy force is smallest when the angles between lamilloy and rotation axis are 90°and 270°. The surface heat transfer coefficient is lowest and the effect of buoyancy force is biggest when the angles between lamilloy and rotation axis are 0°and 180°. The effects of Coriolis force and buoyancy force are researched separately. The effect of Coriolis force in parallel to the lamilloy on flow is more remarkable than that perpendicular to the lamilloy.
