Third-order upwind finite element computation of the incompressible Navier-Stokes equations Part I. Computation of flow around rectangular cylinders Original Research Article

Aerodynamic behaviours of two-dimensional unsteady flows around rectangular cylinders are numerically investigated by third-order upwind finite: element computation of the incompressible Navier-Stokes equations. A turbulence model, such as the two-equation model, is not incorporated in the computational scheme, so that the rectangular cylinders, at depth-breadth ratios from 0.7 to 4, to be considered, are located in a uniform flow. It is found that the numerical results of flows around the rectangular cylinders, obtained by using the third-order upwind finite element scheme, are in good agreement with other computational and experimental results.
