    • Domain growth in binary mixtures at low temperatures 

      Lacasta Palacio, Ana María; Hernández Machado, Aurora; Sancho, Jose Maria; Toral Garcés, Raúl (The American Physical Society, 1992-03-01)
      Article
      Open Access
      We have studied domain growth during spinodal decomposition at low temperatures. We have performed a numerical integration of the deterministic time-dependent Ginzburg-Landau equation with a variable, concentration-dependent ...
    • Efectes calòrics en l’estat sòlid induïts per camps hidrostàtics 

      Dalmases Ceamanos, Marc (Universitat Politècnica de Catalunya, 2014-09)
      Master thesis (pre-Bologna period)
      Open Access
      Aquest projecte s’emmarca en la fase d’investigació fonamental dels efectes calòrics resultants de l’aplicació d’un camp hidrostàtic. L’objectiu és valorar les mostres seleccionades com a possibles candidates per a futures ...
    • Effects of domain morphology in phase-separation dynamics at low temperature. 

      Lacasta Palacio, Ana María; Sancho, Jose Maria; Hernández Machado, Aurora; Toral, Raul. (American Physical Society, 1993-09-01)
      Article
      Open Access
      We present numerical results of the deterministic Ginzburg-Landau equation with a concentration-dependent diffusion coefficient, for different values of the volume fraction phi of the minority component. The morphology of ...
    • Etude pour la mise au point de l'Emission Acoustique en ambiance cryogénique 

      Laguna Salvado, Laura (Universitat Politècnica de Catalunya, 2010-03-31)
      Bachelor thesis

    • Freeze desalination by the integration of falling film and block freeze concentration techniques 

      Zambrano, A.; Ruiz Pardo, Ruth Yolanda; Hernández Yáñez, Eduard; Raventós Santamaria, Mercè; Moreno, F. L. (2018-06-15)
      Article
      Open Access
      Block and falling film freeze concentration are two technologies that separate water by freezing,with the potential to desalinate seawater. In this study, the integration of two freeze concentration techniques as an ...
    • Multiphysics modeling and experimental validation of low temperature accumulator for cryogenic space propulsion systems 

      Torras Ortiz, Santiago; Castro González, Jesús; Rigola Serrano, Joaquim; Morales Ruíz, Sergio; Riccius, Jorg; Leiner, Johannes (2019-01-01)
      Article
      Restricted access - publisher's policy
      Within the framework of Low Thrust Cryogenic Propulsion (LTCP) systems, a low-temperature accumulator acting as thermal energy storage tank is an interesting option for cyclical processes under intermittent firings avoiding ...
    • Subenfriadores criogénicos nitrógeno: aportación a la metodología para el diseño 

      Ruiz Mansilla, Rafael (Universitat Politècnica de Catalunya, 1994-10-24)
      Doctoral thesis
      Open Access
      Se establece la metodología, incluyendo la formulación necesaria, para el diseño térmico de subenfriadores criogénicos n2(i)-n2(i), observando en todo momento criterios de optimización para con los diferentes parámetros y ...
    • Summer heatwaves trends and hotspots in the Barcelona metropolitan region (1914–2020) 

      Serra de Larrocha, Carina; Lana Pons, Francisco Javier; Martínez Santafé, Maria Dolors; Arellano Ramos, Blanca; Roca Cladera, Josep; Biere Arenas, Rolando Mauricio (Springer, 2024-03-06)
      Article
      Open Access
      Daily maximum, TX, and minimum, TN, temperatures recorded at Fabra Observatory, for the period 1914–2020 (from June to September), have permitted to identify the daytime and night time heatwaves, HWs, at the Barcelona ...
