Experimental test of the crossover between the inertial and the dissipative range in a turbulent swirling flow. Debue, P., Kuzzay, D., Saw, E., Daviaud, F., Dubrulle, B., Canet, L., Rossetto, V., & Wschebor, N. Physical Review Fluids, 3(2):24602, American Physical Society, 4, 2018. Website doi abstract bibtex 3 downloads The kinetic energy spectrum of high-Reynolds turbulent swirling flows is experimentally studied. This spectrum, obtained from direct measurements in space, exhibits nearly two decades of Kolmogorov k −5/3 decay in the inertial range of scales. Beyond this regime, in the dissipative range of scales, a crossover to a stretched exponential decay on scale k 2/3 is observed, in full agreement with a recent theoretical prediction based on nonperturbative renormalization group theory.
