As a vital part of the pre-swirl air supply system, the rotating receiver hole will affect the
cooling air quality supplied to turbine rotor blades of an aero-engine. It is concerned about …

In marine gas turbines, variations in rotational speed occur all the time. To ensure adequate
cooling effects on the turbine blades, the valves need to be adjusted to change the pressure …

The pre-swirl system has the ability to decrease the air supply temperature so as to improve
the cooling performance and the operating life for turbine rotating blade. In this paper, a test …

Considerable progress in development and application of computational fluid dynamics
(CFD) for aeroengine internal flow systems has been made in recent years. CFD is regularly …

The pre‐swirl system can transfer the cooling air from the compressor to the turbine rotor
blades with a lower relative total temperature to avoid extreme thermal shock. This work …

In order to separately describe the dominating loss mechanisms in pre-swirled cooling air
delivery systems, discharge, temperature and velocity measurements were performed for …

The pre-swirl system is of great importance for temperature drop and cooling air supply. This
study aims to investigate the influencing mechanism of heat transfer, nonuniform …

The pre-swirl system of an aero engine provides cooling air with suitable temperature and
pressure for turbine blades, rarely contributing to thrust. However, the traditional pre-swirl …

The accuracy of computational fluid dynamics (CFD) for the prediction of flow and heat
transfer in a direct transfer preswirl system is assessed through a comparison of CFD results …

This paper compares heat transfer measurements from a preswirl rotor–stator experiment
with three-dimensional (3D) steady-state results from a commercial computational fluid …
