Numerical simulation of laminar flow past a circular cylinder
TLDR
In this article, an implicit pressure-based finite volume method is used for time-accurate computation of incompressible flow using second order accurate convective flux discretisation schemes, which is validated against measurement data for mean surface pressure, skin friction coefficients, the size and strength of the recirculating wake for the steady flow regime and also for the Strouhal frequency of vortex shedding and the mean and RMS amplitude of the fluctuating aerodynamic coefficients for the unsteady periodic flow regime.About:

Solver-in-the-Loop: Learning from Differentiable Physics to Interact with Iterative PDE-Solvers
TL;DR: In this article, the problem of reducing numerical errors of iterative PDE solvers and comparing different learning approaches for finding complex correction functions is addressed. But the authors find that previously used learning approaches are significantly outperformed by methods that integrate the solver into the training loop and thereby allow the model to interact with the PDE during training, yielding improvements in accuracy with stable rollouts of several hundred recurrent evaluation steps.

Alex Main,Guglielmo Scovazzi +1 more
TL;DR: A new embedded finite element method for the linear advection–diffusion equation and the laminar and turbulent incompressible Navier–Stokes equations, based on the idea of shifting the location where boundary conditions are applied from the true to a surrogate boundary.

Three-dimensional Floquet stability analysis of the wake of a circular cylinder
TL;DR: In this paper, a global numerical stability analysis of the periodic wake of a circular cylinder for Reynolds numbers between 140 and 300 is presented, showing that the two-dimensional wake becomes (absolutely) linearly unstable to three-dimensional perturbations at a critical Reynolds number of 1885±10.
