Fluid Acceleration in the Bulk Turbulence of Dilute Polymer Solutions
Alice M. Crawford, Nicolas Mordant, Haitao Xu +1
We report experimental measurements of Lagrangian accelerations in the bulk of intense turbulent flows of dilute polymer solutions by following tracer particles with a high-speed o…
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…
Evolution of geometric structures in intense turbulence
Haitao Xu, Nicholas T. Ouellette, Eberhard Bodenschatz
We report measurements of the evolution of lines, planes, and volumes in an intensely turbulent laboratory flow using high-speed particle tracking. We find that the classical chara…
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…
Pair Dispersion in Turbulence
Mickael Bourgoin, Nicholas T. Ouellette, Haitao Xu +2
Turbulent mixing of liquids and gasses is ubiquitous in nature. It is the basis of all industrial fluid mixing processes, and it determines the spread of pollutants or bioagents in…
