Physics-informed neural networks for gravity currents reconstruction from limited data
Mickaël Delcey, Yoann Cheny, Sébastien Kiesgen de Richter
The present work investigates the use of physics-informed neural networks (PINNs) for the 3D reconstruction of unsteady gravity currents from limited data. In the PINN context, the…
Laminar mixed convection in an eccentric annular horizontal duct for a thermodependent non-Newtonian fluid
N Ait Messaoudene, A Horimek, C Nouar +1
The present work focuses on the study of mixed convection of a purely viscous shear-thinning fluid in a horizontal annular eccentric duct. The inner and outer cylinders are heated…
Hydrodynamic force on a small squirmer moving with a time-dependent velocity at small Reynolds numbers
T. Redaelli, F. Candelier, R. Mehaddi +2
We calculate the hydrodynamic force on a small spherical, unsteady squirmer moving with a time-dependent velocity in a fluid at rest, taking into account convective and unsteady fl…
Second-order inertial forces and torques on a sphere in a viscous steady linear flow
Fabien Candelier, Rabah Mehaddi, Bernhard Mehlig +1
We compute the full set of second-order inertial corrections to the instantaneous force and torque acting on a small spherical rigid particle moving unsteadily in a general steady…
Unsteady and inertial dynamics of an active particle in a fluid
T. Redaelli, F. Candelier, R. Mehaddi +1
It is well known that the reversibility of Stokes flow makes it difficult for small microorganisms to swim. Inertial effects break this reversibility, allowing new mechanisms of pr…
Mixing and formation of layers by internal wave forcing
Yvan Dossmann, Florence Pollet, Philippe Odier +1
The energy pathways from propagating internal waves to the scales of irreversible mixing in the ocean are not fully described. In the ocean interior, the triadic resonant instabili…
Inertial drag on a sphere settling in a stratified fluid
R. Mehaddi, F. Candelier, B. Mehlig
We compute the drag force on a sphere settling slowly in a quiescent, linearly stratified fluid. Stratification can significantly enhance the drag experienced by the settling parti…
Shear-banding and Taylor-Couette instability in thixotropic yield stress fluids
Mathieu Jenny, Sébastien Kiesgen de Richter, Nicolas Louvet +1
In the present work, we study the flow of thixotropic yield stress fluids between two concentric cylinders. In order to take into account the thixotropy, the constitutive relation…
Cluster-based reduced-order modelling of a mixing layer
Eurika Kaiser, Bernd R. Noack, Laurent Cordier +7
We propose a novel cluster-based reduced-order modelling (CROM) strategy of unsteady flows. CROM combines the cluster analysis pioneered in Gunzburger's group (Burkardt et al. 2006…
Analysis of the incompressibility constraint in the Smoothed Particle Hydrodynamics method
Kamil Szewc, Jacek Pozorski, Jean-Pierre Minier
Smoothed particle hydrodynamics is a particle-based, fully Lagrangian, method for fluid-flow simulations. In this work, fundamental concepts of the method are first briefly recalle…
Liquid Atomization out of a Full Cone Pressure Swirl Nozzle
Nicolas Rimbert, Guillaume Castanet
A thorough numerical, theoretical and experimental investigation of the liquid atomization in a full cone pressure swirl nozzle is presented. The first part is devoted to the study…
Asymptotic analysis of chaotic particle sedimentation and trapping in the vicinity of a vertical upward streamline
J. R. Angilella
The sedimentation of a heavy Stokes particle in a laminar plane or axisymmetric flow is investigated by means of asymptotic methods. We focus on the occurrence of Stommel's retenti…
Crossover between Rayleigh-Taylor Instability and turbulent cascading atomization mechanism in the bag-breakup regime
Nicolas Rimbert, Guillaume Castanet
The question whether liquid atomization (or pulverization) resorts to instability dynamics (through refinements of Rayleigh-Plateau, Rayleigh-Taylor or Kelvin-Helmholtz mechanism)…
A simple model for turbulence intermittencies based on self-avoiding random vortex stretching
Nicolas Rimbert
Whether turbulence intermittencies shall be described by a log-Poisson, a log-stable pdf or other distributions is still debated nowadays. In this paper, a bridge between polymer p…
Simulation of a particle-laden turbulent channel flow using an improved stochastic Lagrangian model
Boris Arcen, Anne Tanière
The purpose of this paper is to examine the Lagrangian stochastic modeling of the fluid velocity seen by inertial particles in a nonhomogeneous turbulent flow. A new Langevin-type…
Statistics of particle dispersion in Direct Numerical Simulations of wall-bounded turbulence: results of an international collaborative benchmark test
C. Marchioli, A. Soldati, J. G. M. Kuerten +6
In this paper, the results of an international collaborative test case relative to the production of a Direct Numerical Simulation and Lagrangian Particle Tracking database for tur…
Contribution to the modeling of a liquid film flowing down inside a vertical circular tube
Samuel Ndoumbe, François Lusseyran, Boujema Izrar
This note focuses on the development of a 2D model of a thin liquid film flowing down inside a vertical pipe. This model is based on the large wavelength assumption and valid for h…
