(Universitat Politècnica de Catalunya, 2011-07-14)
Projecte Final de Màster Oficial
Accés obertLa 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
(Universitat Politècnica de Catalunya / Politecnico di Milano, 2014)
Treball Final de Grau
Accés obert
Realitzat a/amb: Politecnico di MilanoThis 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 ... -
Control de les emissions emeses pels vehicles mitjançant els canisters
(Universitat Politècnica de Catalunya, 2021-07-02)
Treball Final de Grau
Accés obertEn aquest treball de final de grau s’estudia la formació dels gasos contaminants en els vehicles. Per poder entendre la problemàtica que causen les emissions vehiculars en la salut humana i en el medi ambient, s’ha d’analitzar ... -
Dynamics of water vapor flux and water separation processes during evaporation from a salty dry soil
(Elsevier, 2011-01)
Article
Accés restringit per política de l'editorialEvaporation 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
(Universitat Politècnica de Catalunya, 2019-05-27)
Treball Final de Grau
Accés obertL’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
(Universitat Politècnica de Catalunya, 2012-06)
Projecte Final de Màster Oficial
Accés restringit per decisió de l'autorEn 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
(Americah Physical Society, 1999-01-31)
Article
Accés obertWe 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 ... -
Henry's constant of helium in liquid alkali metals
(2024-02)
Article
Accés obertThe determination of the solubility of helium in liquid lithium and in lead-lithium eutectic systems is of crucial importance for the assessment of the reliability, safety and efficiency of future nuclear reactor plants ... -
Increasing stratification as observed by satellite sea surface salinity measurements
(Nature, 2022-12-01)
Article
Accés obertChanges in the Earth’s water cycle can be estimated by analyzing sea surface salinity. This variable refects the balance between precipitation and evaporation over the ocean, since the upper layers of the ocean are the ... -
Numerical and experimental investigation of a vertical LiBr falling film absorber considering wave regimes and in presence of mist flow
(2016-11-01)
Article
Accés obertThe 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
(The Icelandic Geotechnical Society (IGS), 2019)
Text en actes de congrés
Accés restringit per política de l'editorialSoils 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
(2019-01-01)
Article
Accés obertPrevious 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 ... -
Unstructured Conservative Level-Set (UCLS) simulations of film boiling heat transfer
(Springer, 2023)
Text en actes de congrés
Accés restringit per política de l'editorialA novel unstructured conservative level-set method for film boiling is introduced. The finite-volume discretization of transport equations is performed on collocated unstructured grids. Mass transfer is driven by thermal ... -
