    • Design and implementation of a second stage nozzle for a low cost mini-launcher 

      Arias Novo, Ernest (Universitat Politècnica de Catalunya, 2011-03-31)
      Master thesis (pre-Bologna period)
      Open Access
      This study is addressed to design and build a nozzle for a second stage of a solid propellant APCP (Ammonium Perchlorate Composite Propellant) based as a part of an EETAC grand. We will use the simulator Moon2.0 to design ...
    • Disseny d'un test de severitat per a components de bombes d'injecció 

      Domeyó Fauró, Sergi (Universitat Politècnica de Catalunya, 2009-06)
      Master thesis (pre-Bologna period)
      Restricted access - author's decision
      Les noves lleis referents al respecte del medi ambient afecten plenament al món de l’automoció. En quan a emissions, lleis com la nova EURO 5 obliguen a que els futurs vehicles emetin la meitat d’emissions que els que ...
    • Estudio del chorro Diesel producido por un inyector de actuación directa en condiciones no reactivas 

      Vera Sotillo, Alberto (Universitat Politècnica de Catalunya, 2013-07)
      Master thesis (pre-Bologna period)
      Open Access
      La evolución de los motores Diesel en la última década ha sido propulsada principalmente por las estrictas leyes ambientales y los altos costos del combustible. El último desarrollo tecnológico en el campo de los inyectores ...
    • Influence of LPG injection on the performance and emissions of turbocharged diesel engine 

      Martinez Maresco, Roger (Universitat Politècnica de Catalunya / Univerza Ljubljani, 2009)
      Master thesis (pre-Bologna period)
      Restricted access - author's decision
      Influence of the LPG injection on engine performance and emissions of turbocharged diesel engine was analyzed. LPG injection increases effective efficiency of the engine at high loads thereby also increasing emissions ...
    • Study of available turbulence and cavitation models to reproduce flow patterns in confined flows 

      Coussirat Núñez, Miguel Gustavo; Moll, Flavio; Cappa, E. Franco; Fontanals García, Alfred (2016-09)
      Article
      Restricted access - publisher's policy
      Cavitating flow in nozzles is a complex flow which implies a highly turbulent two-phase one. An accurate simulation which improves some numerical results found in the literature was achieved by means of an extensive ...
