En pocos años, este evento se ha consolidado como una plataforma anual de referencia para presentar, discutir y difundir los desarrollos más relevantes en el ámbito de las energías renovables marinas, con especial énfasis en la energía eólica y oceánica. Al igual que en ediciones anteriores, esta convocatoria aspira a reforzar dichos objetivos, generando un entorno de convivencia científica que combine la investigación puntera, la formación de jóvenes investigadores, la relación con la industria y espacios de intercambio que fortalezcan nuestra comunidad. En este contexto, la VII Jornada Internacional de Energía Eólica y Marina ofrece una oportunidad única para reunir a expertos, académicos y profesionales del sector con el fin de compartir avances e identificar retos comunes. El control avanzado y la inteligencia computacional, junto con las nuevas tecnologías de conversión y gestión de la energía, se revelan como herramientas esenciales para afrontar desafíos globales como el cambio climático y la resiliencia de las infraestructuras críticas. Con las contribuciones de esta edición, buscamos no solo impulsar el estado del arte, sino también crear nuevas sinergias que pongan el conocimiento generado al servicio de la sociedad. Finalmente, expresamos nuestro sincero agradecimiento a los autores por la calidad de sus trabajos, así como al Comité Científico y a los revisores por su rigurosa labor de evaluación, garantía del nivel técnico de este congreso. Esperamos que estas actas sirvan como referencia duradera para la comunidad investigadora y que este encuentro en Burgos sea fructífero para todos.

M.; Muñoz Rujas, Natalia; Aguilar Romero, Fernando; Montero García, Eduardo This work reports the experimental density data for the binary mixtures of n-heptane or methylcyclohexane + di-isopropyl ether, measured over the full composition range between 0.1 and 140 MPa, and for temperatures from 298.15 to 393.15 K, by means of a vibrating tube densitometer calibrated with an uncertainty of 0.0007 g·cm–3. Then, the experimental density data were fitted using a Tait-like equation to derive mixing thermodynamic coefficients, including the isobaric expansivity and isothermal compressibility. Finally, the excess volumes of the abovementioned binary mixtures were calculated, and their nonideal behavior was investigated. 2020-10-01T00:00:00Z https://hdl.handle.net/10259/11444 Isobaric Vapor–Liquid Equilibria at 50.0, 101.3, and 200.0 kPa. Density and Speed of Sound at 101.3 kPa and 298.15 K of Binary Mixtures HFE-7100 + 2-Propanol Muñoz Rujas, Natalia; Rubio Pérez, Gabriel; Montero García, Eduardo; Aguilar Romero, Fernando Isobaric vapor–liquid equilibria (VLE) at 50.0, 101.3, and 200.0 kPa, have been measured for the binary system methyl nonafluorobutyl ether (x1) HFE-7100 + (1 – x1) 2-propanol. Thermodynamic consistency was checked by applying the Wisniak point to point and area tests, as well as the Fredenslund point to the point test. Vapor–liquid equilibrium data have been correlated by means of Wilson, NRTL, and UNIQUAC equations. The three binary systems show positive azeotropes at every measured pressure. Densities and speeds of sound were determined experimentally at 101.3 kPa and at 298.15 K. Excess volumes, isentropic compressibilities, and deviations in isentropic compressibility were calculated from experimental data. The Redlich–Kister polynomial was used to correlate excess properties upon mixing, showing a good agreement between experimental and calculated values. 2020-05-01T00:00:00Z https://hdl.handle.net/10259/11443 Consistent DSC and TGA Methodology as Basis for the Measurement and Comparison of Thermo-Physical Properties of Phase Change Materials Müller, Lukas; Rubio Pérez, Gabriel; Bach, Andreas; Muñoz Rujas, Natalia; Aguilar Romero, Fernando; Worlitschek, Jörg Measuring thermo-physical properties of phase change materials (PCM) in a consistent and reliable manner is essential for system layout of thermal energy storages and correspondingly material selection. Only if basic properties are assessed in a comparable way a selection process leads to the top candidate for any given application and thus enhances market penetration of renewable energy sources coupled with thermal energy storage. In this study, we focus on differential scanning calorimetry (DSC) and thermogravimetric analysis (TGA) as basic assessment techniques and develop consistent measurement procedures to create a database with comparable results. We show consistency of the measured results through analysis of coefficient of variation (CV), being in the mean 1.69%, 0.05%, 0.06% and 4.00% for enthalpy, melting onset, melting peak and maximum operating temperature, respectively. Overall, 23 PCM have been measured with the presented methodology, which was mainly possible due to the reduced measurement and preparation time per PCM compared to standard techniques, while achieving similar accuracy and precision. 2020-10-01T00:00:00Z
