On the theory of fast projection methods for high-order Navier-Stokes solvers

M Karam, T Saad - Journal of Computational Physics, 2023 - Elsevier
We propose a new framework for the design of fast-projection solvers for the Navier-Stokes
equations using Runge-Kutta integrators. The framework uses the full nonlinear equations …
