The tubeless vortex reducer was used to reduce the pressure drop in a cavity with radial
inflow. In previous studies, the mechanism of vortex breakdown in tubeless vortex reducers …

Modern aero-engines require a high cycle temperature for effective performance. Particular
attention is paid to the ICAS (internal cooling air system), particularly the air-bleed system …

The research purpose of this paper is to explore the influence of the baffle plate on the
airflow in the rear cavity of the centrifugal impeller and optimize the performance of the …

Experimental research was performed to determine the pressure drop in a rotating cavity
with radial inflow. In order to decrease the pressure loss across the rotating cavity, three …

The flow characteristics of a tubed vortex reducer, which was used to reduce the pressure
drop in an aeroengine air bleed system, were studied in this paper. Accurate prediction of …

The rise in temperature and pressure ratios for both turbine and compressor intrinsically
require an increased secondary air system performance. The more demanding operating …

To improve the work performance of the air bleed system (ABS) in an aero-engine, a new
type of hybrid vortex reducer system (HVR) is designed, and related experimental tests are …

Temperature and pressure ratios in gas turbines have grown over time to increase the
performance and efficiency of the engine. This, in turn, has required improvements to the …
