Experimental study of endwall flow in a low-speed linear compressor cascade: effect of over-tip leakage [PDF]
, 2017 This paper describes the study of endwall flow modification due to over-tip leakage flow in axial compressor blades. Un-shrouded axial compressor stator and rotor blades in aero-engines and land based gas turbines are subjected to over-tip leakage flow ...

Analysis of the Formation Mechanism of Secondary Tip Leakage Vortex (S-TLV) in an Axial Flow Pump
Machines, 2022 Studies on the tip leakage vortex (TLV) are extensive, while studies on the secondary tip leakage vortex (S-TLV) are rare. To advance the understanding of the formation mechanism of the S-TLV, turbulent cavitating flows were numerically investigated ...

Leakage Flow Characteristics in Blade Tip of Shaft Tubular Pump
Journal of Marine Science and Engineering, 2023 The shaft tubular pump device is widely used in various water diversion projects because of its ultra-low head and large flow characteristics. Due to the tip clearance between the blade and the shroud, it is easy to cause hydraulic mechanical performance

Spatio-temporal second-order quantum correlations of surface plasmon polaritons
, 2015 We present an experimental methodology to observe spatio-temporal second-order quantum coherence of surface plasmon polaritons which are emitted by nitrogen vacancy color centers attached at the apex of an optical tip.
