Numerical Simulation of 3D Flow in Rotation Cup of Rotor Spinning
To make design of rotation cup device more reasonable, the air-flow-field in rotation cup should be analyzed. Numerical simulation is conducted on 3D flow in rotation cup of rotor spinning with Fluent and the simulation results reveal the airflow characteristics as: the vortex is generated in rotation cup and the airflow speed decreases gradually on slip plane; the airflow in the type of V accumulation groove is more intensive and a little faster than that in the type of U accumulation groove in the same condition; there exist two strands of reverse direction airflow in accumulation groove; there exist two high pressure regions on slip plane and accumulation groove.
