A Review of Secondary Flow in Inertial Microfluidics [PDF]
Micromachines, 2020 Inertial microfluidic technology, which can manipulate the target particle entirely relying on the microchannel characteristic geometry and intrinsic hydrodynamic effect, has attracted great attention due to its fascinating advantages of high throughput,

Secondary Lip Flow in a Cyclone Separator [PDF]
Flow, Turbulence and Combustion, 2023 Three secondary flows, namely the inward radial flow along the cyclone lid, the downward axial flow along the external surface of the vortex finder, and the radial inward flow below the vortex finder (lip flow) have been studied at a wide range of flow ...

Secondary flow in a laminar boundary layer developing over convergent-divergent riblets
International Journal of Heat and Fluid Flow, 2020 Convergent-divergent (C-D) riblets are a type of bio-inspired surface pattern. They are known to induce secondary flow in a boundary layer that may point to their potential for surface friction drag reduction and flow separation control. In this paper, a

Experimental Study of Secondary Flow in Narrow and Sharp Open-Channel Bends [PDF]
Journal of Applied Fluid Mechanics, 2023 Secondary flow is a prominent feature of channel bends; it alters the streamwise velocity and bed shear stress distributions. Experiments were conducted to investigate the complex pattern of secondary flow in a narrow and sharp open-channel bend and the ...

A Thermohydraulic Performance of Internal Spiral Finned Tube Based on the Inner Tube Secondary Flow
Energies, 2022 In this article, the BSL k-ω model was chosen as the turbulence model to simulate the heat transfer and flow characteristics of the proposed tubes inserted with internal spiral fins when the Re was set as 3000 to 17,000. The numerical results agreed well
