  • The distribution of forces induced by rotating limited lamilloy was researched by numerical simulation. It was emphasized that because the cool fluid was heated, the centrifugal force was reduced with the increase of the radius, and became lower near the wall, but higher far from the wall.The Coriolis force directed y was evident in the areas of inlet and outlet, but it could be ignored in the middle of lamilloy. The Coriolis force directed z was evident in the areas of inlet and outlet, and increased slowly with the increase of the rotation speed and radius. The buoyancy force caused by centrifugal force increased the velocity of fluid near impact zoo, but in the other zoo and near the wall, it decreased the velocity of fluid, and far from the wall, it also increased the velocity of fluid. In the middle lamilloy, centrifugal force and buoyancy force caused by centrifugal force played a leading role.
