✦ Synopsis

We present a comparison of the performance of vortex and pseudospectral methods in two reference flows: a homogeneous turbulent flow at low Reynolds number and a vortex reconnection case at a moderate Reynolds number. The results should contribute to a better understanding of the accuracy of vortex methods in both resolved and underresolved simulations.

## Abstract This paper presents an integral vorticity method for solving three‐dimensional Navier–Stokes equations. A finite volume scheme is implemented to solve the vorticity transport equation, which is discretized on a structured hexahedral mesh. A vortex sheet algorithm is used to enforce the

The present algorithm is developed to calculate three-dimensional incompressible, turbulent and steady flows in hydraulic turbomachines and installations. The code is based on a characteristic based method for the solution of the incompressible Navier-Stokes equations, coupling the continuity and mo

A spectral element technique is examined, which builds upon a local discretization within the spectral space. To approximate a given system of equations the domain is subdivided into nonoverlapping quadrilateral elements, and within each element a discretization is found in the spectral space. The d

In this work a comparative study of two versions of the projection algorithm used either for time integration or as an iterative method to solve the three-dimensional incompressible Navier -Stokes equations is presented. It is also shown that these projection algorithms combined with the finite elem
