This paper evaluates the use of helium xenon binary gas mixture having molecular weight of
15 g/mole in an axial compressor of terrestrial nuclear power plants as working fluid. Pure …

The increase of the thrust/weight ratio of aircraft engines is extremely restricted by different 3-
D flow loss mechanisms. One of them is the corner separation that can form at the junction …

Three-dimensional corner separation seriously deteriorates the aerodynamic performance
of a compressor blade. In this study, the complicated vortex dynamics and loss mechanism …

Axial compressors in aero engines are prone to suffering a breakdown of orderly flow when
operating at the peak of the pressure rise characteristic. The damaging potential of …

Aircraft axial compressors are commonly designed with high load that generates strong
secondary flow and produces high secondary loss. To deal with this problem, profiled end …

Unsteady flow in the hub endwall region has long been a hot topic in the turbomachinery
community. However important it is to the performance of the whole engine, the coherent …

Combining tandem cascades and curved vanes can mitigate the separation in highly loaded
compressor cascades. Flow loss mechanisms in curved tandem cascades are crucial for …

The complex flow characteristics in the tip region of a tandem cascade with tip clearance
have been calculated and analyzed using Delayed Detached Eddy Simulation (DDES). The …

In order to improve the performance and eliminate flow separations, boundary layer
suction/aspiration, was carried out in an ultra-highly loaded (UHL) supersonic compressor …

This paper describes an aerodynamic design optimization of a highly loaded compressor
stator blade using parameterized free-form deformation (FFD). The optimization …
