...Xiao Qu; Meng Wu; Yanfeng Zhang; Xingen Lu; Liunan Li; Yuyan Jiang; Junqiang Zhu The coupling effect between the complex vortex system and the rim purge flow in the endwall region of a high-lift low-pressure turbine (LPT) will significantly influence the evolution of secondary flow...

... of secondary flow phenomena. This article experimentally investigates the secondary flow effects in the 3D-optimized shrouded stator of the TUDa-GLR-OpenStage, representative of a transonic high-pressure compressor front stage, and its susceptibility to typical hub leakage flows. The impact of stator hub...

...Zhengshuai Du; Le Cai; Yingjie Chen; Songtao Wang; Hongfei Tang; Jun Zeng The endwall contouring has proven to be an effective technique in controlling the impacts of secondary flow within turbomachinery. A baseline cascade with the original axisymmetric endwall (BASE) has been redesigned...

...Fernando Gisbert; David Cadrecha; Patxi Apoita This paper analyzes the effect of the inlet end-wall boundary layer on the secondary flow of a low pressure turbine airfoil cascade at Reynolds number 2 × 10 5 using RANS and implicit large-eddy simulations (LES). The results are compared against...

... to determine the endwall flow streams in a low-speed low-pressure linear turbine cascade vane using a numerical approach. The study includes two sections. The first section includes an attempt to understand different secondary flow streams available at the endwall. The location of the horseshoe vortex...

... holes and blade shape, which change the secondary flow and flow non-uniformity of the internal cooling flow. This study conducted an experimental and numerical analysis to characterize the secondary flow and flow non-uniformity in a realistic internal cooling serpentine passage. Magnetic resonance...

..., the circumferentially averaged coefficient of secondary kinetic energy at the mixed-out plane (Fig. 10 ) shows a similar result to its upstream counterpart. However, as would be expected, the total amount of secondary flow at each spanwise location is reduced (due to washing out) and as such the differences between...
