We develop a model to numerically study the dynamics of vortex streets in channel flows. Previous work has studied the vortex wakes of specific vortex generators. Here, we study a wide range of vortex wakes including regular and reverse von Karman streets with various strengths, geometries, and Reynolds numbers (Re) by applying a smoothed von Karman street as an inflow condition. We find that the spatial structure of the inflow vortex street is maintained for the reverse von Karman street and… 

Electromagnetically generated vortex streets in a narrow channel

Numerical assessment of canopy blocking effect on partly-obstructed channel flows: from perturbations to vortices

The evolution and characteristics of large-scale vortices are critical for understanding temporal and spatial exchange of mass and momentum. Using a validated depth-averaged large-eddy simulation

Advancing thermal performance through vortex generators morphing

The design of rigid vortex generators (RVG) influences the thermal performance of various technologies. We employed Discrete Adjoint-Based Optimization to show the optimal development of vortex

Improved convection cooling in steady channel flows

We find steady channel flows that are locally optimal for transferring heat from fixed-temperature walls, under the constraint of a fixed rate of viscous dissipation (enstrophy = $Pe^2$), also the

Behavior of synchronous and asynchronous spatially oscillating planar liquid jets in tandem

Understanding the behavior of oscillating liquid jets in tandem is vital for improving the efficacy of numerous industrial applications. An interpretation of their behavior in the terms of

Airfoil-shaped self-agitator for convective heat transfer enhancement

Bio-inspired self-agitator for convective heat transfer enhancement

Convective heat transfer plays an important role in both the fundamental research and the development of high-performance heat exchangers. Inspired by blades of grass vibrating in the wind, we

Residence time control in micromixers with vortex shedding

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



On vortex street wakes

The flow in the wake of a two-dimensional blunt-trailing-edge body was investigated in the Reynolds number range, Reynolds number being referred to base height, 1·3 × 104 to 4·1 × 104. The effects of

On the inversion of the von Kármán street in the wake of a confined square cylinder

This paper considers the incompressible two-dimensional laminar flow around a square cylinder symmetrically positioned in a channel. In this type of flow, even if vortices of opposite sign are

Vortex wakes of a flapping foil

We present an experimental study of a symmetric foil performing pitching oscillations in a vertically flowing soap film. By varying the frequency and amplitude of the oscillation we visualize a

Transitions in the wake of a flapping foil.

It is shown that the transition from a B vK wake to a reverse BvK wake precedes the actual drag-thrust transition and the significance of the present results in the analysis of flapping systems in nature is discussed.

The vortex-shedding process behind two-dimensional bluff bodies

Using a variety of flow-visualization techniques, the flow behind a circular cylinder has been studied. The results obtained have provided a new insight into the vortex-shedding process. Using

An inviscid model of two-dimensional vortex shedding

An inviscid model of two-dimensional vortex shedding behind a square-based section is developed. The model uses a discrete-vortex approximation for the free shear layers. The motion of the shear

On the symmetry breaking instability leading to vortex shedding

It is well known that at early stages an impulsively started flow past a circular cylinder consists of twin vortices which are images of one another by reflection through the mid-plane. While the

Vortex Dynamics in the Cylinder Wake

Since the review of periodic flow phenomena by Berger & Wille (1972) in this journal, over twenty years ago, there has been a surge of activity regarding bluff body wakes. Many of the questions
