Residence time control in micromixers with vortex shedding [PDF]

open access: yes, 2017
Residence time control is an important indicator of micromixer design. When using vortex shedding to enhance mixing efficiency in a micromixer, the relationship between residence time and vortex shedding becomes important; if residence time is shorter ...

Numerical Investigation on Vortex Shedding from a Hydrofoil with a Beveled Trailing Edge

open access: yesModelling and Simulation in Engineering, 2015
To better understand the vortex shedding mechanism and to assess the capability of our numerical methodology, we conducted numerical investigations of vortex shedding from truncated and oblique trailing edges of a modified NACA 0009 hydrofoil. The hybrid

Vortex motion around a circular cylinder

open access: yes, 2011
The motion of a pair of counter-rotating point vortices placed in a uniform flow around a circular cylinder forms a rich nonlinear system that is often used to model vortex shedding.

Lagrangian and spectral analysis of the forced flow past a circular cylinder using pulsed tangential jets [PDF]

open access: yes, 2012
We numerically investigate the influence of pulsed tangential jets on the flow past a circular cylinder. To this end a spectral-Lagrangian dual approach is completed on the basis of time-series data.

Transient Simulations Based on the Wake of a Tapered Circular Cylinder

open access: yesFluids
Numerical techniques have been developed to study flow structures in the wake behind a tapered circular cylinder via computational fluid dynamics. The Reynolds number, based on the mean diameter of the tapered cylinder, is 4 × 103; here, the boundary ...

Three-dimensional flows around low-aspect-ratio flat-plate wings at low Reynolds numbers [PDF]

open access: yes, 2009
Three-dimensional flows over impulsively translated low-aspect-ratio flat plates are investigated for Reynolds numbers of 300 and 500, with a focus on the unsteady vortex dynamics at post-stall angles of attack. Numerical simulations, validated by an oil

The appearance of two lock-in states in the vortex flow around an in-line forced oscillating circular cylinder

open access: yesEPJ Web of Conferences, 2014
In this study, the flow features of vortex shedding from a circular cylinder forced-oscillating in the in-line direction were investigated by use of flow visualization experiment and numerical simulation at the Reynolds number Re=620, with varied ...
