Effect of Re λ and Rouse numbers on the settling of inertial droplets in homogeneous isotropic turbulence

Autor: Martin Obligado, Daniel Odens Mora, Alberto Aliseda, Alain H. Cartellier

Publikováno v: Physical Review Fluids
Physical Review Fluids, American Physical Society, 2021, 6 (4), pp.044305. ⟨10.1103/PhysRevFluids.6.044305⟩

International audience; 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, we observe that the modifications of the set

Physical Review Fluids, American Physical Society, 2021, 6 (7), pp.074801. ⟨10.1103/PhysRevFluids.6.074801⟩

We analyze theoretically and experimentally the triadic resonance instability (TRI) of a plane inertial wave in a rotating fluid. Building on the classical triadic interaction equations between helical modes, we show by numerical integration that the

International audience; We analyze the vector nulls of velocity, Lagrangian acceleration, and vorticity, coming from direct numerical simulations of forced homogeneous isotropic turbulence at Re λ ∈ O([40 − 600]). We show that the clustering of

Estimating the integral length scale on turbulent flows from the zero crossings of the longitudinal velocity fluctuation

Autor: Martin Obligado, Daniel Odens Mora

Publikováno v: Experiments in Fluids
Experiments in Fluids, Springer Verlag (Germany), 2020, 61 (9), ⟨10.1007/s00348-020-03033-2⟩

The integral length scale ( $$\mathcal {L}$$ ) is considered to be characteristic of the largest motions of a turbulent flow, and as such, it is an input parameter in modern and classical approaches of turbulence theory and numerical simulations. Its

Experimental estimation of turbulence modification by inertial particles at moderate $\text{Re}_λ$

Autor: Martin Obligado, Alain H. Cartellier, Daniel Odens Mora

Publikováno v: Physical Review Fluids
Physical Review Fluids, American Physical Society, 2019, 4 (7), ⟨10.1103/PhysRevFluids.4.074309⟩

International audience; We advance a method to estimate the carrier-flow dissipation $ɛ_p$ in the presence of inertial sub-Kolmogorov particles at moderate Re${}_λ$. Its foundations rely on the unladen flow dissipation calculation using the Rice th

Energy cascades in active-grid-generated turbulent flows

Publikováno v: Physical Review Fluids
Physical Review Fluids, American Physical Society, 2019, 4 (10), ⟨10.1103/PhysRevFluids.4.104601⟩

International audience; The energy cascade and diverse turbulence properties of active-grid-generated turbulence were studied in a wind tunnel via hot-wire anemometry. To this end, two active grid protocols were considered. The first protocol is the

Pitfalls Measuring 1D Inertial Particle Clustering

We perform 1D Voronoi analysis on a time series from an optical probe detecting the passage of particles in a homogeneous. isotropic turbulent flow. The Voronoi analysis is unable to identify clustering in the particle locations along the measuring �
