The effect of and Rouse numbers on the settling of inertial particles in homogeneous isotropic turbulence
Daniel Odens Mora, Martin Obligado, Alberto Aliseda +1
We present an experimental study on the settling velocity of dense sub-Kolmogorov particles in active-grid-generated turbulence in a wind tunnel. Using phase Doppler interferometry…
Clustering of vector nulls in homogeneous isotropic turbulence
D. O. Mora, M. Bourgoin, P. D. Mininni +1
We analyze the vector nulls of velocity, Lagrangian acceleration, and vorticity, coming from direct numerical simulations of forced homogeneous isotropic turbulence at $Re_λ\in [40…
Estimating the integral length scale on turbulent flows from the zero crossings of the longitudinal velocity fluctuation
Daniel Odens Mora, Martin Obligado
The integral length scale () is considered to be characteristic of the largest motions of a turbulent flow, and as such, it is an input parameter in modern and classic…
Energy cascades in active-grid-generated turbulent flows
D. O. Mora, E. Muñiz Pladellorens, P. Riera Turró +2
The energy cascade and diverse turbulence properties of active-grid-generated turbulence were studied in a wind tunnel via hot-wire anemometry. To this aim, two active grid protoco…
