Flows of Dense Granular Media (2008, background): “…with classical hydrodynamics problems, more complex flow configurations have been analyzed, such as dam-break problems (Lajeunesse et al. 2004, Lube et al. 2004), coating-like problems (Deboeuf et al. 2006, Felix & Thomas 2004), mixing experiments (Ottino & Khakhar 2000), split Couette…”
Segregation, recirculation and deposition of coarse particles near two-dimensional avalanche fronts (2009, methodology): “One approach, which has been used successfully by Doyle et al. (2007) to model collapsing column experiments (Lajeunesse, Mangeney-Castelnau & Vilotte 2004; Lube et al. 2004; Balmforth & Kerswell 2005) is to prescribe the deposition rate d .”
Continuum modelling and simulation of granular flows through their many phases (2014, background): “Columns with a larger aspect ratio of height to width will tend to flatten out more due to macro-inertial effects, which has been observed in discrete element simulations by Lacaze & Kerswell (2009) and experimentally by Lube et al. (2004).”
The granular column collapse as a continuum: validity of a two-dimensional Navier–Stokes model with a μ(I)-rheology (2011, methodology): “The granular column collapse experiment was initially designed to constrain the factors controlling the run-out (or maximum distance reached by the flowing material) of natural catastrophic granular flows (Lajeunesse et al. 2004; Lube et al. 2004).”
Study of the collapse of granular columns using two-dimensional discrete-grain simulation (2005, neutral): “After briefly recalling and commenting on the experimental results obtained by other authors (Lube et al. 2004; Lajeunesse et al. 2004; Balmforth & Kerswell 2005) in § 3, the different regimes of spreading are qualitatively described and scaling laws are established in § 4.”
On the use of Saint Venant equations to simulate the spreading of a granular mass (2005, background): “Since the normalized deposit morphology is shown to depend only on a, simple empirical relations can be found relating morphological variables, e.g., the runout distance, the maximum height of the deposit, etc., to the aspect ratio [Lajeunesse et al. 2004; Lube et al., 2004].”
Fundamental changes of granular flow dynamics, deposition, and erosion processes at high slope angles: Insights from laboratory experiments (2014, background): “…the characteristics of the deposit to the initial dimensions of the granular column (initial height, radius, and aspect ratio, i.e., height over width) [ Balmforth and Kerswell , 2005; Lajeunesse et al. , 2004, 2005; Lube et al. , 2004, 2005; Siavoshi and Kudrolli , 2005; Lacaze et al. , 2008].”
A new SPH-based approach to simulation of granular flows using viscous damping and stress regularisation (2017, background): “Lube et al. (2004) and Lajeunesse et al. (2004) were the first to conduct experiments of this type using cylinder granular columns to investigate the mechanisms of granular flow, such as the relationship between the initial aspect ratio (the ratio of initial height to initial width) and the…”
Granular collapse in two dimensions (2005, background): “This corroborates the conclusion of Lajeunesse et al. (2004) and softens that of Lube et al. (2004).”
Numerical modeling of 2‐D granular step collapse on erodible and nonerodible surface (2009, methodology): “experimental results in the literature [Lajeunesse et al., 2004, 2005; Lube et al., 2004, 2005, 2007; Siavoshi and Kudrolli, 2005; Balmforth and Kerswell, 2005], both in terms of coefficient and exponent values.”
Gravity currents: a personal perspective (2006, background): “To counter this, Lube et al. (2004) carried out experiments with the granular media, of initial height hi , raised a height H before a constraining plug was released.”
