Ítem Acceso Abierto Hidrodinámica de elementos de amortiguamiento del movimiento vertical de plataformas eólicas flotantes(Asociación de Ingenieros Navales y Oceánicos de España, 2021-10-21) Saavedra Ynocente, Leandro; Molinelli Fernández, E.; Soriano Gómez, C.; Bezunartea Barrio, A.; Oria Escudero, J.; Marón Loureiro, Adolfo"Within the framework of collaborative projects of the National Research Program, INTA - CEHIPAR and CEHINAV (UPM) are carrying out a project on the hydrodynamic analysis of damping mechanisms of vertical motions (heave) in floating offshore wind turbines (FOWT) in which scale effects are evaluated of the hydrodynamic phenomena in order to increase damping, added mass and at the same time contributing to the structural resistance of the platform. The evaluation of the scale effects has been carried out through experimental tests at three different scales in a simplified model and at three different frequencies and amplitudes. It was verified with the analysis of the experimental tests that there are no significant scale effects, therefore the next phases are only carried out with a single model scale, the one with the largest scale. The increase in damping for this type of floating offshore wind turbines has been evaluated through different solutions. They were chosen based on numerical calculations by adding several disc setups at the bottom of one of the platform legs, in four different configurations: single disc, double discs of equal size and double unequal discs in two configurations. In these tests, the non-intrusive experimental technique of particle image velocimetry (PIV) and forces measurement on the cylinder in forced oscillations through of a vertical actuator has been used."Ítem Restringido Medición de flujos complejos mediante técnicas no invasivas(AINE, 2020-12-14) Molinelli Fernández, E.; Soriano Gómez, C.Ítem Restringido Monitorización de embarcaciones y ensayos de modelos a escala(AINE, 2020-12-14) Molinelli Fernández, E.; Soriano Gómez, C.; Carrillo Hontoria, Eloy; Castaño Martínez, PedroPublicación Acceso Abierto Monotorización de la salud estructural de un material compuesto mediante sensores FBGS(Sociedad Española de Materiales, 2022-06-02) González Gallego, Manuel; Martínez Vicente, Juan Luis; Terroba, F.; Frövel, M.; Ministerio de Ciencia e Innovación (MICINN)En este trabajo se presenta la campaña de ensayos biaxiales llevada a cabo con el fin de caracterizar la influencia de cargas transversales en los sensores de fibra óptica en redes de Bragg (FBGS) con diferentes materiales de recubrimiento. Para la caracterización de los sensores FBG se ha optado por un diseño de probeta con geometría cruciforme, como medio material estructural de análisis del campo de deformaciones. En estas probetas, los sensores se han colocado en la zona central, alineada con dos de los brazos y perpendicular a los otros dos. Los ensayos biaxiales se han prolongado hasta alcanzar el 70% de la carga máxima soportada por el material compuesto, con el que está fabricada la probeta cruciforme. Las probetas ensayadas se han laminado a partir de tejido unidireccional reforzado con fibra de carbono y resina epoxi, utilizado en estructuras monolíticas navales. Este proyecto de investigación se enmarca en el Convenio de colaboración existente entre INTA y la UCLM.Ítem Acceso Abierto Optimización de carenas de buques con operatividad multifunción(Asociación de Ingenieros Navales y Oceánicos de España, 2022-10-21) Molinelli Fernández, E.; Soriano Gómez, C.; Carrillo Hontoria, Eloy; Pamies Durá, J.; Senent Gómez, F."In last years, the design and operational requirements of ships are increasing significantly to meet the specifications and requirements of the shipowners. This makes ships more innovative and with less conventional characteristics to achieve better operability, having to achieve high standards in each of the operations to which they are going to be destined for not complying with the basis of its design. These atypical vessels of multifunctional design make that the semi-empirical and statistical methods used up to now offer results with more uncertainty than expected compared with the results obtained through experimental tests, since they would not be within the ranges of all the dimensionless relationships available in the databases that compose these methods. In this work, we present a recent case in which a large discrepancy is detected between the semiempirical methods and the results obtained experimentally. In this particular case, the ship, which although initially has a conventional characterization, is modified in its design with dimensionless relationships outside the operating ranges due to the introduction of multifunctionality parameters. This discrepancy forces the designer to optimize the geometry in due to the initial estimation with the semi-empirical methods because did not correspond to reality, forcing to continue iterating in the design of the geometry. An optimization is carried out in the ship geometry based on CFD analysis and the experimental results obtained and with this, a better power-speed curve is obtained, complying with the requirements imposed by the owner."Ítem Restringido Recuperación de piezas obsoletas mediante técnicas de escaneado láser.
