Turbulent two-dimensional incompressible flows are studied by means of a mixed Euler-Lagrange method. Transported properties are the vorticity ζ the turbulent kinetic energy k, and a turbulent characteristic frequency ω. This approach avoids the use of a permanent grid and the discretization of the convective terms. It is suitable for multibody configurations, particularly when wake/body interaction occurs.
