In this paper, the influence of tip leakage flow on the 3-d viscous flow field is investigated for different blade tip gap shapes under the condition of rotatinghub or stationary hub.
The Sun is the hub of a huge rotating system consisting of nine planets, their satellites, and numerous small bodies, including asteroids, comets, and meteoroids.
