Multiturbulence Report Summary

Project ID: 320560
Funded under: FP7-IDEAS-ERC
Country: United Kingdom

Final Report Summary - MULTITURBULENCE (Fractal-generated fluid flows: new flow concepts, technological innovation and fundamentals)

A law describing the rate of dissipation of turbulent energy was discovered in a variety of turbulent flows. In turbulent jets and wakes this law appears with specific jet and wake growth rates and specific entrainment properties which differ from what one can read in turbulence textbooks. Implications for turbulence modelling, engineering and the environment are deep and wide ranging. On the technological side, a new dynamic mixer concept was introduced and tested. It uses fractal profile blades and reduces mixing time by half. It also offers higher mechanical and energy efficiency in high viscosity fluid mixing.
