In the fall jet and in the dissipation basin appear high turbulence and aeration phenomena, that cannot be correctly studied by the classical methodologies. The methods used in Computational Fluid Dynamics (CFD) are based on numerical solution of the Navier-Stokes and averaged Reynolds equations, together with turbulence models of different complexity grade: vortex´s algebraic models for the viscosity (k-¿, RNG k-¿, k-¿) and Reynolds Stress Models (RSM). Taking into account these problematic and in function of different experimental results, the Hidr@m group is carrying out different studies to characterize velocities (Doppler instrument), pressures (piezoresistive transducers) and aeration (optical fibre). These laboratory results are useful as a base to validate and calibrate some commercial programs CFD.
