Turbulence and self-similarity in finite systems
- 26 Downloads
We discuss the self-similar behaviour of a system as small as an atomic nucleus which flows at Reynolds numbers larger than 10. We simulate the flow in a classical molecular approach which mimics the collision of two fast moving heavy ions and calculate high-order velocity structure functions to compare to data obtained in a fully developed turbulent flow at Reynolds numbers larger than 500. A comparison to the Kolmogorov theory and to the β-model is also given. We estimate the fractal dimensionD.
