Parameterization of Convective Transport in a Lagrangian Particle Dispersion Model and Its Evaluation [PDF]

open access: yes, 2007
This paper presents the revision and evaluation of the interface between the convective parameterization by Emanuel and Živkovic´-Rothman and the Lagrangian particle dispersion model “FLEXPART” based on meteorological data from the European Centre for ...

Review of CFD modelling techniques for single‐phase and multiphase flow in static mixers

open access: yesThe Canadian Journal of Chemical Engineering, EarlyView.
This review synthesizes computational fluid dynamics (CFD) approaches for static mixers, linking hydrodynamics to pressure drop, particle/droplet distributions, mixing metrics, and heat‐transfer performance to guide modelling choices and design decisions. Abstract Static mixers enable compact and low‐energy intensification.

Review: Hydrocodes for Structural Response to Underwater Explosions

open access: yesShock and Vibration, 1999
The applicability of the various hydrocode methodologies (Lagrangian, Eulerian, Coupled Eulerian–Lagrangian, and Arbitrary Lagrangian–Eulerian) for structural response to underwater explosions is reviewed.

Combining Column Generation and Lagrangian Relaxation [PDF]

open access: yes
Although the possibility to combine column generation and Lagrangian relaxation has been known for quite some time, it has only recently been exploited in algorithms. In this paper, we discuss ways of combining these techniques.

Lagrangian Averaging, Nonlinear Waves, and Shock Regularization [PDF]

open access: yes, 2005
In this thesis, we explore various models for the flow of a compressible fluid as well as model equations for shock formation, one of the main features of compressible fluid flows.

Preventing wall deposition in duct flows: The role of particle number density and flow direction

open access: yesThe Canadian Journal of Chemical Engineering, EarlyView.
Abstract Particle deposition in wall‐bounded turbulent flows is a challenge in many industries, including pneumatic conveying, filtration, and related applications. When particles accumulate near boundaries, they reduce transport efficiency, alter near‐wall flow structures, and cause blockage.

Stochastic reconstruction of gappy Lagrangian turbulent signals by conditional diffusion models

open access: yesCommunications Physics
Understanding and predicting the motion of small objects in turbulent flows is essential for applications in atmospheric science and oceanography. However, missing velocity data along their trajectories remains a major challenge.

Lagrangian flows for vector fields with gradient given by a singular integral [PDF]

open access: yes, 2013
We prove quantitative estimates on ows of ordinary di erential equations with vector field with gradient given by a singular integral of an L1 function.

A Geometric Characterization of Steady Laminar Flow

open access: yesCommunications on Pure and Applied Mathematics, EarlyView.
ABSTRACT We study the steady states of the Euler equations on the periodic channel or annulus. We show that if these flows are laminar (layered by closed non‐contractible streamlines which foliate the domain), then they must be either parallel or circular flows.

Lectures on special Lagrangian geometry [PDF]

open access: yes, 2001
We introduce special Lagrangian submanifolds in C^m and in (almost) Calabi-Yau manifolds, and survey recent results on singularities of special Lagrangian submanifolds, and their application to the SYZ Conjecture.
