@article{Mercado2011LagrangianSO, title={Lagrangian statistics of light particles in turbulence}, author={Julian Martinez Mercado and Vivek N. Prakash and Yoshiyuki Tagawa and Chao Sun and Detlef Lohse}, journal={Physics of Fluids}, year={2011}, volume={24}, pages={055106} }

We study the Lagrangian velocity and acceleration statistics of light particles (micro-bubbles in water) in homogeneous isotropic turbulence. Micro-bubbles with a diameter db = 340 ?m and Stokes number from 0.02 to 0.09 are dispersed in a turbulent water tunnel operated at Taylor-Reynolds numbers (Re?) ranging from 160 to 265. We reconstruct the bubble trajectories by employing three-dimensional particle tracking velocimetry. It is found that the probability density functions (PDFs) of the…

Lagrangian measurements of water droplets in grid generated wind tunnel turbulence at a Taylor Reynolds number of R(lambda)=250 and an average Stokes number (St) of approximately 0.1 show that the inertial particles selectively sample the fluid field and are less likely to experience regions of the fluid undergoing the largest accelerations.
