Webcoherent measurements with free evolution times Tthat exceed the ensemble coherence time T 2 ˘1= inh for the g !e i transitions. The free evolution time T can be made as long as the time T ee for which the superposition of je 1iand je 2iwill maintain coherence: for hyper ne and nuclear spin states in solids, T ee can be much longer than the ... Web18 nov. 2024 · The coherent structures arising during flat-plate boundary layer transition at Mach number 3.4 are investigated using a custom-built hyper-rate imaging system. The evolution of transitional structures is investigated in … Turbulent flows are complex multi-scale and chaotic motions that need to be classified into more elementary components, referred to coherent turbulent structures. Such a structure must have temporal coherence, i.e. it must persist in its form for long enough periods that the methods of time-averaged statistics can be applied. Coherent structures are typically studied on very large scales, but can be broken down into more elementary structures with coherent properties of thei… hawk with white breast and brown spots
