Experimental measurement of acceleration correlations and pressure structure functions in high Reynolds number turbulence
Haitao Xu, Nicholas T. Ouellette, Dario Vincenzi +1
We present measurements of fluid particle accelerations in turbulent water flows between counter-rotating disks using three-dimensional Lagrangian particle tracking. By simultaneou…
Lagrangian Structure Functions in Turbulence: A Quantitative Comparison between Experiment and Direct Numerical Simulation
L. Biferale, E. Bodenschatz, M. Cencini +4
A detailed comparison between data from experimental measurements and numerical simulations of Lagrangian velocity structure functions in turbulence is presented. By integrating in…
Modification of the turbulent energy cascade by polymer additives
Nicholas T. Ouellette, Haitao Xu, Eberhard Bodenschatz
By tracking small particles in the bulk of an intensely turbulent flow, we show that even a very small concentration of long-chain polymers disrupts the usual turbulent energy casc…
