CDIF - Centre de Diagnòstic Industrial i Fluidodinàmica
La recerca del CDIF està relacionada amb el comportament dinàmic d'estructures confinades excitades per fluids. La recerca del comportament dinàmic requereix del estudi de les excitacions generades per un fluid i la resposta estructural per determinar els comportaments vibratoris i les deformacions. L'aplicació principal està en les turbomàquines hidràuliques (sector energies renovables).
