• Acoustic and hydrodynamic analysis of the flow around an aerofoil with trailing-edge serrations (2012, methodology): “A non-reflecting zonal boundary condition is used to avoid spurious pressure-oscillations from the outflow boundary (Sandberg & Sandham 2006), which is subject to the passage of nonlinear disturbances, i.e. vortical structures.”
• Direct numerical simulations of forced and unforced separation bubbles on an airfoil at incidence (2008, background): “At the downstream exit boundary (ξ±), which will be subject to the passage of nonlinear fluid structures, a zonal characteristic boundary condition (Sandberg & Sandham 2006) is applied for increased effectiveness.”
• Applying Machine Learnt Explicit Algebraic Stress and Scalar Flux Models to a Fundamental Trailing Edge Slot (2018, methodology): “Characteristic boundary conditions were used for the freestream and at the outlet a zonal characteristic boundary condition was employed [16] using 30 streamwise points.”
