Investigation and Improvement of T-Tail Junction Flow Separation for a Demonstration Aircraft

open access: yesAerospace, 2022
Flow separation is easily induced at the junctions of aircraft components, and for aircraft with T-type tails, in particular, it can lead to loss of directional stability under a small sideslip angle. In the reported study, improved delayed detached eddy

Research on the Influence of Inflow Conditions on the Aerodynamic Performance of a Tandem Cascade [PDF]

open access: yesJournal of Applied Fluid Mechanics, 2022
We perform a thorough numerical analysis of the impact of inflow conditions on the aerodynamic performance of a tandem cascade. In particular, we investigate the effects of the incidence angle and the inlet boundary layer (IBL) thickness on the three ...

Corner effect and separation in transonic channel flows [PDF]

open access: yesJournal of Fluid Mechanics, 2011
An investigation into parameters affecting separation in normal shock wave/boundary layer interactions (SBLIs) has been conducted. It has been shown that the effective aspect ratio of an experimental facility (defined as δ*/tunnel width) is a critical factor in determining when shock-induced separation will occur. Experiments examining M∞ = 1.4 and 1.5

Corner Separation Control Using a New Combined Slotted Configuration in a High-Turning Compressor Cascade under Different Solidities

open access: yesEnergies, 2021
In order to comprehensively control the corner separation and the blade trailing edge (TE) separation in a high-turning compressor stator cascade, this research proposes a new combined slotted configuration consisting of one full-span slot and two blade ...

The Study of the Concave Corner Flow Separation in the Hypersonic Flow.

open access: yesJournal of the Japan Society for Aeronautical and Space Sciences, 1998
To clarify the action of the rudder of HSTs, a hypersonic convex flow separation was studied. In a hypersonic flow the rudder can not act efficiently because of the boundary layer separation, so that studies of that are needed. In previous studies, the hypersonic convex flow separation was not studied because the surface pressure gradient of the convex

The impact of variable fillets on corner separation in a liner compressor cascade

open access: yesJournal of the Global Power and Propulsion Society, 2023
The performance of highly-loaded compressor is retricted by complex three-dimensional corner separation. The fillet with variable geometry around the blade has shown its potential in reducing the corner separation. However, there are no specific design criteria for fillets.

Identification of corner separation modelling in axial compressor stage [PDF]

open access: yesE3S Web of Conferences, 2020
The paper presents a study of corner separations in hub to blade region at various operation conditions towards compressor stall. It is known that for compressor flows with low or none separations computation fluid dynamics with RANS methods work quite ...

Arc Effect on Charged Ion Migration in Capillary Zone Electrophoresis Using Hybrid Finite Element and Particle-in-Cell Method

open access: yesJournal of Thermal Science and Technology, 2013
Analytes separated by capillary zone electrophoresis are governed by ion migration. The study proposed a hybrid finite element and particle-in-cell method to simulate ion migration in the cross-channel capillary zone electrophoresis system.
