Research

Turbulent flows with particles

Particles in a turbulent channel flow
Particles in a turbulent channel flow

Direct numerical simulations of turbulent suspension flows are carried out with the Force-Coupling Method in plane Couette and pressure-driven channel configurations. Through investigation of particle modification on two distinct flow configurations, we were able to show the specific response of turbulent structures and the modulation of the fundamental mechanisms composing the regeneration cycle of turbulence in the buffer layer of near-wall region. Especially for pressure-driven flow, the particles enhance the lift-up and let it act continuously whereas the particles do no significantly alter the streak breakdown process. It is observed that particles increase the transverse r.m.s. flow velocity fluctuations and they break down the flow coherent structures into smaller, more numerous and sustained eddies, preventing the flow to relaminarize at the single-phase critical Reynolds number.

Suspension dynamics at low Reynolds number

Particles clogging the entrance of a pore
Particles clogging the entrance of a pore

The dynamic formation of 3D structures of microparticle aggregates blocking the flow through straight microchannels or pore entrance is investigated by direct numerical simulation of the coupled motion of particles and fluid. We use the Force Coupling Method to handle simultaneously multibody hydrodynamic interactions of confined flowing suspension together with particle–particle and particle–wall surface interactions leading to adhesion and aggregation of particles. We show that physical–chemical interactions, modeled by DLVO forces, are essential features which control the blockage dynamics and aggregate structure. In the absence of DLVO repulsive forces, plugging is characterized by the temporal reduction of the bulk permeability when increasing the volume fraction of the flowing suspension up to 20%. The network of jammed particles collapses when the force chains among the particles overcome the flow stress. The build-up and the collapse of the jammed phase at the pore entrance induce temporal permeability fluctuations.

Phytoplanton in turbulence

Preferential accumulation of phytoplankton cells in turbulence
Preferential accumulation of phytoplankton cells in turbulence

The motility of microorganisms is often biased by gradients in physical and chemical properties of their environment, with myriad implications on their ecology. Patchiness plays a fundamental role in phytoplankton ecology by dictating the rate at which individual cells encounter each other and their predators. We demonstrate experimentally that Heterosigma akashiwo forms striking patches within individual vortices and prove with a mathematical model that this patchiness results from the coupling between motility and shear. We show that fluid acceleration or gravity reorient gyrotactic plankton, triggering small-scale clustering. We experimentally demonstrate this phenomenon by studying the distribution of the phytoplankton Chlamydomonas augustae within a rotating tank and find it to be in good agreement with a new, generalized model of gyrotaxis. When this model is implemented in a direct numerical simulation of turbulent flow, we find that fluid acceleration or gravity generates multifractal plankton clustering, with faster and more stable cells producing stronger clustering.

Active suspensions

Collective dynamics of active squirmers
Collective dynamics of active squirmers

We present a new development of the force-coupling method (FCM) to address the accurate simulation of a large number of interacting micro-swimmers. Our approach is based on the squirmer model, which we adapt to the FCM framework, resulting in a method that is suitable for simulating semi-dilute squirmer suspensions. Other effects, such as steric interactions, are considered with our model. Using this methodology, we investigate the emergence of polar order in a suspension of squirmers and show that for large domains, both the steady-state polar order parameter and the growth rate of instability are independent of system size.

Bubbly flows

Turbulent structures in a Taylor-Couette flow
Turbulent structures in a Taylor-Couette flow

We investigate bubble dispersion in turbulent Taylor-Couette flow. The aim of this study is to describe the main mechanisms yielding preferential bubble accumulation in near-wall structures of the flow. The simulations are compared and validated with experimental and numerical data from literature. The second part of this study is devoted to bubble dispersion. Bubble accumulation is analyzed by comparing the dispersion obtained with the full turbulent flow field to bubble dispersion occurring at lower Reynolds numbers in previous works. Several patterns of preferential accumulation of bubbles have been observed depending on bubble size and the effect of gravity.

Heat and Mass transfer, Chemical Reactions

Mass transfer around particles
Mass transfer around particles

We study mass transfer towards a solid spherical catalyst particle experiencing a first order irreversible reaction coupled to an external laminar flow. Chemical species get diffused from fluid phase to solid phase through the particle surface where an internal first order irreversible chemical reaction takes place within the porous catalyst particles. Then, we study mass transfer through random assemblies of fixed spherical catalyst particles experiencing an external convective-diffusive fluid stream. We address the problem by performing direct numerical simulations with fully internal-external coupling using concentration and flux continuity boundary conditions at the solid-fluid interface. We derive a model for the profiles of cup-mixing concentration, the average of mean surface and the average of mean volume concentration of the particles along the bed.

Mixing in particulate suspension

PLIF measurements of mixing in Taylor vortices
PLIF measurements of mixing in Taylor vortices

The flow and mixing in a Taylor–Couette device have been characterized by means of simultaneous particle image velocimetry and planar laser-induced fluorescence (PLIF) measurements. Concentration of a passive tracer measurements was used to investigate mixing efficiency for different flow patterns. Neutrally buoyant particles with increasing volume concentration enhance significantly mixing of a passive tracer injected within the gap between two concentric cylinders. To achieve reliable experimental data, index matching of both phases is used together with a second PLIF channel. From this second PLIF measurements, dynamic masks of the particle positions in the laser sheet are determined and used to calculate accurately the segregation index of the tracer concentration. Experimental techniques have been thoroughly validated through calibration and robustness tests. Three particle sizes were considered, in two different flow regimes to emphasize their specific roles on the mixing dynamics.

Centrifugal separation of solid-liquid suspensions

Particle spatial distribution in a hydrocyclone
Particle spatial distribution in a hydrocyclone

There are many circumstances where hydrocyclone performance and dense flow are intertwined, such as for example when feed solids flow exceeds hydrocyclone capacity during continuous operations. The work reported here, which is part of an ongoing research effort to develop a robust CFD model for prediction of hydrocyclone performance, focuses on hydrocyclone operation under high solids concentration. The paper presents the basic physics framework that accounts for solid–liquid and solid–solid interactions under hydrocyclone’s swirling flow. Operating conditions that are past the transition from spray to rope regime are deliberately chosen for this purpose. Model predictions are validated by comparison with solids split and separation curves measured on a 100 mmdiameter hydrocyclone. CFD model predictions permit taking an insightful look at the inside of a hydrocyclone under extreme operating conditions, which would be difficult to achieve experimentally.
