This image depicts a 2D cross section of turbulent flow created by shining a laser into a cylinder to create a vertical plane. A fog machine was then used to blow thick fog into the plane near the point the light hit a solid background, which can be seen on the left side of the image. It can be seen from the distribution of the fog that the flow originates near where the laser hits the wall and flows to the right side of the image, spreading and dissipating as its flows right. This image shows a fascinating depiction of turbulence, displaying lots of vortices and chaotic behavior. The laser highlights the density of the fog as the brighter regions are created by more light reflecting off fog particles. The setup is show below.
