• Characteristic boundary conditions for direct simulations of turbulent counterflow flames (2005, background): “As an alternative, the nonreflecting inflow conditions maintain a good control of the inlet flow variables while reducing spurious wave reflections at the inflow boundaries [ 22 , 23].”
• The effect of wavy leading edges on aerofoil-gust interaction noise (2013, background): “The blending factor s smoothly varies on the thickness of the sponge zone LS, from zero in the physical domain to some positive value s0 at the outer boundaries of the sponge zone, where non-reflecting characteristic BC [27,28] are applied.”
• Airfoil noise reductions through leading edge serrations (2015, methodology): “Inflow and outflow conditions in horizontal and vertical directions and also non-penetrating wall condition for the plate surface are implemented using generalized characteristic boundary conditions (GCBC) [17] with periodic boundary conditions in span wise direction.”
• Computational aeroacoustics: progress on nonlinear problems of sound generation (2004, methodology): “For non-planar boundaries, this procedure can also be applied to body-fitted, generalized coordinate systems [246,247].”
• On the reduction of aerofoil–turbulence interaction noise associated with wavy leading edges (2016, methodology): “In addition to the sponge layers used, characteristics-based non-reflecting boundary conditions (Kim & Lee 2000) are applied at the far boundaries in order to prevent any outgoing waves from returning to the computational domain.”
