The application of unsteady incompressible flow phenomenon over the bluff bodies has
received the attention of many researchers due to the rich and complex physics …

Nonlinear convective terms pose the most critical issues when a numerical discretization of
the Navier–Stokes equations is performed, especially at high Reynolds numbers. They are …

The benchmarking case of flow past a circular cylinder at the Reynolds number (Re) of 3900
is computed with two open-source codes, OpenFOAM and Nektar++, which are based on …

The turbulent flow around a square cylinder at Reynolds number 22, 000 (based on the
cylinder diameter and the inflow velocity) is studied by means of direct numerical simulation …

First-and second-order accurate numerical methods, implemented for CPUs, underpin the
majority of industrial CFD solvers. Whilst this technology has proven very successful at …

We present a study of the turbulence cascade on the centreline of an inhomogeneous and
anisotropic near-field turbulent wake generated by a square prism at a Reynolds number of …

It is well known that the flow past a circular cylinder at critical Reynolds number combines
flow separation, turbulence transition, reattachment of the flow, and further turbulent …

To draw concrete pictures of the hierarchy of multiscale coherent vortices in turbulence
behind a cylinder and to reveal their sustaining mechanism, we conduct direct numerical …

Abstract This study employs Partially-Averaged Navier-Stokes (PANS) equations to simulate
the flow around a smooth circular cylinder at Reynolds number 3900. It intends to evaluate …

One of the strengths of the discontinuous Galerkin (DG) method has been its balance
between accuracy and robustness, which stems from DG's intrinsic (upwind) dissipation …
