摘要：A hybrid vortex reducer combining the de-swirl inlet hole and the vortex tubes was proposed, the effect of drag reduction and bleed air was numerically studied, and the effects of rotating Reynolds number and dimensionless inlet mass flow on internal flow field structure and pressure loss were analyzed. It was found that in the inflow structure of the hybrid vortex reducer, the static pressure decreased gently in the radial direction and was evenly distributed in the circumferential direction. With the ascension of the dimensionless inlet mass flow or the rotating Reynolds number, the total pressure drop of the inflow structure showed a monotonous increasing trend. Especially, under the conditions of higher rotating Reynolds number and lower dimensionless mass flow, outstanding drag reduction was observed and the corresponding turbulence parameter range of 0.1064-0.3245 was obtained. Compared with the simple disk cavity, the pressure loss of the de-swirl vortex reducer and the tube vortex reducer was reduced by 62.5% and 60.5%, respectively, and the hybrid vortex reducer can reduce the pressure loss by 80.4%, showing a better drag reduction. © 2019, Editorial Department of Journal of Aerospace Power.
