The Final Design of the Long Pipe in CICLOPE
One of the fundamental characteristics of turbulent flows is that the ratio of large to small scales increases drastically with increasing Reynolds number. In standard laboratory apparatus, the fine structure of turbulence becomes exceedingly small, as compared to the size of standard probes, leading to large experimental uncertainties. Therefore an accurate description of the mutual interactions becomes complicate and many questions remains unanswered. The Center for International Cooperation for Long Pipe Experiment (CICLOPE) was established to design a pipe-flow facility (Long Pipe) that, thanks to its large size, has the potential to eliminate these uncertainties. Here we present the final design of the Long Pipe, which is now complete and operative.
