Abstract

Turbulence is one of the greatest unsolved puzzles in science. The complexity of turbulent flows can readily transcend even the top supercomputers. However, it is of vital importance in wind energy, understanding pollutant transport, exchanging of carbon dioxide and oxygen, predicting weather and climate, and many other environmental phenomena. To characterize and quantify complex flows, a measurement technique known as particle image velocimetry (PIV) obtains the instantaneous velocity field by calculating the speed and direction of small tracer particles. In this particular image, the tracer particles are composed of hollow glass spheres and are illuminated by a laser plane. These glowing particles (here, defocused) are then captured in frames using a CCD camera and are processed through a series of algorithms that tracks the particles producing a velocity vector field.
