Fluid Fishbone Effect

Buy Add to Lightbox Download
.The unique fishbone pattern is created by two colliding steams of liquids.  Each stream or jet is created by a 1mm diameter nozzle.  This image if from a series of images where the velocity of the fluid jet is varied from .8 to 3 meters per second.  This pattern is currently the focus of scientists studying the strange world of fluid dynamics.  The pattern is a stable flow state that is a balance of surface tension,  viscosity, momentum, and gravity.  The fluid used in this experiment is 90% glycerol  and 10% water solution with a viscosity of 20cS.   This image was taken with a high speed flash at 1/40,000th of a second at at a magnification of 1x.  This pattern cal also be called the fish effect, herringbone effect, or the fishbone effect.
