  • Characterization of concrete by calibrating thermo-hydraulic multiphase flow models 

    Chaparro Sánchez, Maria Carme; Saaltink, Maarten Willem; Villar Galicia, María Victoria (2015-08-01)
    Article
    Open Access
    Evaporation tests in concrete columns have been analysed by numerical models to characterize the thermo-hydraulic properties and the processes in concrete. Two evaporation tests were performed: a column heated by a lamp ...
  • Comparativa técnica, energética y económica de tres operaciones de concentración en la industria alimentaria: La evaporación, la tecnologia de membranas y la crioconcentración 

    Álvarez Rollán, Alexis (Universitat Politècnica de Catalunya, 2011-07-14)
    Master thesis
    Open Access
    La industria alimentaria se encuentra ante la necesidad de concentrar alimentos líquidos y para ello aplica sistemas tecnológicos que permiten eliminar parte del agua. En la práctica también representa un procedimiento ...
  • Comparison of drop evaporation models on hot surface 

    González Esteve, Adrià (Universitat Politècnica de Catalunya / Politecnico di Milano, 2014)
    Bachelor thesis
    Open Access
    Covenantee:  Politecnico di Milano
    This project is a study of how a sessile drop evaporates on a hot surface. Some existing models of droplet evaporation are explained, understood, simulated and compared. This project also provides an expression of drop ...
  • Dynamics of water vapor flux and water separation processes during evaporation from a salty dry soil 

    Gran Esforzado, Meritxell; Massana, Jordi; Carrera Ramírez, Jesús; Saaltink, Maarten Willem; Olivella Pastallé, Sebastià; Ayora Ibáñez, Carlos; Lloret Morancho, Antonio (Elsevier, 2011-01)
    Article
    Restricted access - publisher's policy
    Evaporation from a salty soil generates salt accumulation near the surface with the subsequent deterioration of the soil quality. Salinization mechanisms are poorly understood despite their global impact. Vapor flux and ...
  • Estudi i caracterització del procés d'adsorció-desorció de LNG en dipòsits de transport Heavy-Duty 

    Vicens Artés, Òscar (Universitat Politècnica de Catalunya, 2019-05-27)
    Bachelor thesis
    Open Access
    L’objectiu d’aquest treball és estudiar i caracteritzar el procés d'adsorció-desorció del vapor del Gas Natural Liquat -LNG en endavant- provinent del dipòsit en transports Heavy-Duty. L’evaporació del LNG es degut a ...
  • Estudio evaporacion de disoluciones acuosas de amoniaco 

    Corruchaga Guerrero, Agustín (Universitat Politècnica de Catalunya, 2012-06)
    Master thesis
    Restricted access - author's decision
    En este trabajo se ha estudiado la evaporación de amoníaco desde disoluciones acuosas para diferentes velocidades de aire. Los valores obtenidos se han comparado con los principales modelos de evaporación encontrados en ...
  • Evaporation and coarsening dynamics with open boundaries 

    Lacasta Palacio, Ana María; Sagués Mestre, Francesc; Sancho, Jose Maria; Sokolov, Igor M. (Americah Physical Society, 1999-01-31)
    Article
    Open Access
    We present a study of the evaporation dynamics of a substance undergoing a coarsening process. The system is modeled by the Cahn-Hilliard equation with absorbing boundaries. We have found that the dynamics, although of ...
  • Numerical and experimental investigation of a vertical LiBr falling film absorber considering wave regimes and in presence of mist flow 

    García Rivera, Eduardo; Castro González, Jesús; Farnós Baulenas, Joan; Oliva Llena, Asensio (2016-11-01)
    Article
    Open Access
    The absorber represents the most critical component in absorption systems and one of the key issues. In this component complex heat and mass transfer phenomena during the absorption process takes place simultaneously. For ...
  • Soil surface boundary condition in desiccating soils 

    Cuadrado Cabello, Agustín; Encalada López, David Alejandro; Ledesma Villalba, Alberto; Prat Catalán, Pere (The Icelandic Geotechnical Society (IGS), 2019)
    Conference report
    Restricted access - publisher's policy
    Soils undergoing desiccation exhibit shrinkage and eventually cracking. That may become an environmental problem in practical applications. From a Geotechnical perspective, it is possible to solve the corresponding ...
  • The evapotranspiration process in green roofs: a review 

    Cascone, Stefano; Coma Arpón, Julià; Gagliano, Antonio; Pérez Luque, Gabriel (2019-01-01)
    Article
    Open Access
    Previous research has shown that most of the green roof benefits are related to the cooling effect. In the literatura available, however, it is still not clear how and how much the evapotranspiration affects the performance ...
  • Vertically resolved precipitation intensity retrieved through a synergy between the ground-based NASA MPLNET lidar network measurements, surface disdrometer datasets and an analytical model solution 

    Lolli, S.; D'Adderio, L.P.; Campbell, J.R.; Sicard, Michaël; Welton, E.J.; Binci, A.; Rea, Alessandro; Tokay, A.; Comerón Tejero, Adolfo; Barragán Cuesta, Rubén; Baldasano Recio, José María; González, Sergio; Bech, Joan; Afflitto, Nicola; Lewis, J.R.; Madonna, Fabio (Multidisciplinary Digital Publishing Institute (MDPI), 2018-07-01)
    Article
    Open Access
    In this paper, we illustrate a new, simple and complementary ground-based methodology to retrieve the vertically resolved atmospheric precipitation intensity through a synergy between measurements from the National Aeronautics ...
