The correlation between the velocity helicity and the energy backscatter is proved in a DNS
case of 256 3-grid homogeneous isotropic decaying turbulence. The helicity is then …

Three-dimensional design is central to all modern compressor design systems, but many of
these methods still rely on a two-dimensional and sectional view of aerodynamics at their …

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 (3D) corner separation in a linear highly loaded compressor cascade is
studied by using delayed detached-eddy simulation (DDES) method. This paper studies the …

The corner separation flow in a highly loaded prescribed velocity distribution (PVD) cascade
has been studied by using DDES method based on SST k–ω model (DDES-SST). The …

Compressor efficiency variation with rotor tip gap is assessed using numerical simulations
on an embedded stage representative of that in a large industrial gas turbine with Reynolds …

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

The aerodynamic stability of an axial compressor stage depends on the rotor and stator.
However, due to the specific design requirements, the evolving flow field and the resulting …

Three-dimensional corner separation is a common phenomenon that significantly affects
compressor performance. Turbulence model is still a weakness for RANS method on …

Regions of three-dimensional separations are an inherent flow feature of the suction surface-
endwall corner in axial compressors. These corner separations can cause a significant total …
