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 …

Vortical flow is generally considered to be a flow with a rotational trend, but vortex regions
vary depending on the vortex identification methods by which they are extracted. In this …

Abstract Three-dimensional (3D) corner separation flow is the main source of losses and
blockages in compressors, and it is vital to the compressor performance. This paper …

The secondary flow in the impeller of an axial flow pump is an important factor affecting the
safe and stable operation of the unit. However, there is still a lack of systematic research on …

As the Reynolds number increases, the large-eddy simulation (LES) of complex flows
becomes increasingly intractable because near-wall turbulent structures become …

Corner separation control is studied in this paper on a linear compressor cascade by
optimizing the proposed blade end slots. In order to decrease risk of the experiment and …
