| Abstract: | A very special rotating cavity with micro-turbine(de-swirl nozzles) was applied to investigate the flow characteristics inside the cavity under three mid rotating speeds.The influence of rotational speed and axial location(six locations) was summarized.The results reveal that the flow is mainly controlled by the inflow inertia force at lower rotating speed,and it is essentially controlled by rotating effect at higher rotating speed and by both factors at transition rotating speed.Then,the distribution of tangential,radial,axial components of velocity and pressure is given. |
