Specific areas of research energy field

The CDIF’s main areas of research are related to the dynamic behaviour of hydraulic turbines and pump-turbines. Dynamic behavior of airfoils. We have our own Doctoral Programme: Fluids, Turbomachines and Fluid Power. This is a Technical University of Catalonia (UPC) qualification.

Fluid dynamic excitation on hydraulic machinery

Rotor stator interaction, cavitation, vortex shedding.Fluid-structure interaction. Unsteady CFD

Structural dynamics

Experimental and numerical (FEM) modal analysis. Fluid-structure interactions. Added mass effects.

CFD Simulation

Numerical simulation of momentum, heat- and mass-transfer problems in turbulent flows related to industrial fluid flows and turbomachines.
