Artificial Compressibility Approaches in Flux Reconstruction for Incompressible Viscous Flow Simulations
Will Trojak, Nagabhushana Rao Vadlamani, James Tyacke +2
Several competing artificial compressibility methods for the incompressible flow equations are examined using the high-order flux reconstruction method. The established artificial…
Utilizing Time-Reversibility for Shock Capturing in Nonlinear Hyperbolic Conservation Laws
Tarik Dzanic, Will Trojak, Freddie D. Witherden
In this work, we introduce a novel approach to formulating an artificial viscosity for shock capturing in nonlinear hyperbolic systems by utilizing the property that the solutions…
Hyperbolic Diffusion in Flux Reconstruction: Optimisation through Kernel Fusion within Tensor-Product Elements
Will Trojak, Rob Watson, Freddie Witherden
Novel methods are presented in this initial study for the fusion of GPU kernels in the artificial compressibility method (ACM), using tensor product elements with constant Jacobian…
Bounds Preserving Temporal Integration Methods for Hyperbolic Conservation Laws
Tarik Dzanic, Will Trojak, Freddie D. Witherden
In this work, we present a modification of explicit Runge-Kutta temporal integration schemes that guarantees the preservation of any locally-defined quasiconvex set of bounds for t…
