This work presents preliminary results of the use of a macroscopic model for numerical simulations of turbulent flows in ducts infested by Limnoperna Fortunei. The computational model was based on the volumetric and temporal averages of the Navier-Stokes equations, in a way that the resulting model allowed simulations of turbulent flows in clean, porous and hybrid media. The averaged mass and momentum conservation equations were written for a representative elementary volume and discretized using the finite volume method, using a SIMPLE algorithm for the treatment of pressure-velocity coupling. A macroscopic $k-\varepsilon $ turbulence model was applied. Simulated results for mean velocity and turbulent kinetic energy distribution and head losses in infested ducts were obtained, discussed and compared to experimental measurements.
