Unified semi‐analytical wall boundary conditions for inviscid, laminar or turbulent flows in the meshless SPH method (2013, methodology): “The tensorial strain rate of the mean velocity field is given by Sa 1=2 rauCrauT ; Violeau and Issa [10] discretised the SPH form the velocity gradient as Grada¹ubº 1 a X b 2F mbuab ˝rwab (12) In the following, for the sake of simplicity, we will drop all overbars denoting Reynolds-averaged velocity”
Permeable and non‐reflecting boundary conditions in SPH (2009, methodology): “These properties are discussed more fully by Violeau and Issa [9] and Basa et al.”
Smoothed particle hydrodynamics model applied to hydraulic structures: a hydraulic jump test case (2010, methodology): “5.3 k-ε Turbulence model Violeau and Issa (2007) used different turbulence models comprising one or two equations, such as the k-ε model, the explicit algebraic Reynolds stress model (EARSM) and the large eddy simulation (LES), and obtained good results for the test case of water column collapse.”
Boundary conditions generated by dynamic particles in SPH methods (2007, methodology): “Experimental points were digitalized from Violeau and Issa (2006).”
Comparisons of weakly compressible and truly incompressible algorithms for the SPH mesh free particle method (2008, methodology): “At a wall, Dirichlet boundary conditions apply to velocity and Neumann conditions should be applied to pressure in both methods (see [24] in terms of WCSPH).”
State-of-the-art of classical SPH for free-surface flows (2010, methodology): “The Electricite de France (EDF) group has successfully used their code to study both incompressible flows (Issa et al. 2005, Lee et al. 2008) and turbulent free-surface flows (Violeau and Issa 2007).”
Application of weakly compressible and truly incompressible SPH to 3-D water collapse in waterworks (2010, methodology): “However, all these neglected effects can be easily accounted for in the coming SPH algorithm when it is proved to be necessary (see e.g. Violeau and Issa (2007) for turbulence; see Hu and Adams (2007) for surface tension).”
Current achievements and future perspectives for projection-based particle methods with applications in ocean engineering (2016, methodology): “Researches on proper modeling of turbulence by either timeaveraged (e.g. Violeau and Issa 2007) or spatially averaged (e.g. sub-particle-scale; Gotoh et al. 2001) turbulencemodels are continuously advancing (e.g. Mayrhofer et al. 2015).”
Shocking results without shocks: Subsonic turbulence in smoothed particle hydrodynamics and moving-mesh simulations (2011, background): “Only a few studies have considered subsonic turbulence in SPH thus far (Violeau & Issa 2007; Monaghan 2011; Robinson & Monaghan 2011) and we are not aware of a comparative analysis of three-dimensional simulations in this regime.”
