Centre for Industrial Diagnostics and Fluid Dynamics
CDIF is home to a team of PhD-level industrial engineers with more than 20 years of experience in vibrations, diagnostics, damage detection and fluid dynamics.
The centre provides technological support to companies in areas related to the diagnostics of electric generation units, especially of the hydroelectric variety.
The centre's main areas of expertise are as follows:
Analysis and diagnosis of vibration problems in machinery
On-site problem-solving; analysis of complex cases using advanced techniques such as signal processing and simulation; diagnosis on the basis of data provided by the company via email; vibrations in pipes; modal analysis.
Fluid dynamics studies
Problem analysis; cavitation; experimental measurements; various simulations; laboratory testing; fluid-structure interaction; structural response.
Collaboration on industrial projects
Fluid-structure interaction; design of small facilities.
Online remote monitoring
Installation of online monitoring equipment; remote supervision of critical machinery from the CDIF's facilities; remote diagnosis on request.
Implementation of vibration-based predictive-maintenance systems; selection of measurement points, positions, acquisition parameters, bands, alarm levels, database preparation, measurement paths, etc.; on-site company personnel training; supervision of measurements carried out by company personnel; large-scale damage detection.
CDIF participates actively in conferences specific to its area of expertise and publishes articles in internationally recognised scientific journals. Additionally, it is involved in the UPC doctoral degree course Mechanical Engineering, Fluids and Aeronautics.
CDIF develops its technological capacities in the following sectors:
Modal analysis of a Francis turbine runner. VATech Zurich (Switzerland).
Measurement and analysis of vibrations in a pump-turbine. Voith Siemens Hydro, Heidenheim (Germany).
The Centre for Industrial Diagnostics and Fluid Dynamics (CDIF UPC) has completed a numerical and experimental study of the dynamic behaviour of pump-turbine vanes submerged in water. The study determined the effects of the added mass of water, the contour, and the rotor on the dynamic response of this type of vane.
Vibration measurements and diagnosis of hydraulic units at the Soutelo and Cortes–La Muela hydraulic plants (Iberdrola).
Measurement of vibrations and analysis of the catamaran Mark1. Naviera Universal.
