Use of a triboelectric generator for a tunable wideband energy harvester and a threshold shock sensor
… outputs. A proof of concept of a threshold shock sensor is proposed that incorporates bi-stability along with the triboelectric effect. A clamped-clamped buckled beam will switch stable states when a threshold shock amplitude is experienced and a voltage peak will occur during this switching …

On the Application of an Output-based Adaptive, Higher-order Finite Element Method to Sonic Boom Propagation
… artificial viscosity is incorporated via a shock sensor PDE approach to handle shock presence, with necessary corrections applied to the DWR error estimate. The VMSD-BR2 method is applied then to a real-world scenario solving the augmented Burgers equation, which models the propagation of …

Shock capturing with PDE-based artificial viscosity for an adaptive, higher-order discontinuous Galerkin finite element method
… greater than the speed of sound, an appropriate shock capturing for higher-order, adaptive methods is necessary. Artificial viscosity can be combined with a higher-order discontinuous Galerkin finite element discretization to resolve a shock layer within a single cell. However, when a nonsmooth …

Numerical Modelling of Shock Wave Boundary Layer Interactions in Aero-engine Intakes at Incidence
… flow to supersonic speeds, terminating with a shock wave. This produces undesirable shock wave boundary layer interactions (SWBLIs). Reynolds-Averaged Navier Stokes (RANS) turbulence models have been shown to be insensitive to the effects of boundary layer relaminarisation present in these …
