Ribbon mixer simulation (VIDEO) University of Birmingham This video is under embargo. Please login to access this video. Caption A ribbon mixer looks standard piece of equipment, but without proper design, the mixing is less than ideal. The video demonstrates a simulation of a ribbon mixer with 30 million particles. Starting with a quarter of them distinctly coloured in orange and tucked away in one corner, we expected them to blend smoothly throughout the system's three alternating stages. Yet the simulation reveals a different story.
