Abstract

Numerical simulations are used to investigate the influence of different de-swirl angles on the flow and heat transfer in rotor-stator cavity system The results show that: de-swirl angle has great influence on the swirl number; radial velocity increases with the increase of de-swirl angle; the smaller de-swirl angle is, the more smooth radial velocity distributes; it is favorable for disc flow and heat transfer when θ=45°.
