  • Análisis de estabilidad Arnoldi de las ondas de Tollmien-Schlichting en fluidos viscosos 

    Montañez Fabrés, Raquel (Universitat Politècnica de Catalunya, 2017-07)
    Bachelor thesis
    Open Access
    En este trabajo se estudia la estabilidad de las ondas Tollmien-Schlichting, que aparecen como una primera fase de la inestabilidad del flujo de Poiseuille plano como paso de laminar a turbulento. Se calcula la curva de ...
  • Characterization of localized solutions of plane Poiseuille flow in very long domains 

    Valera Pascual, Antonio (Universitat Politècnica de Catalunya, 2016-05-24)
    Bachelor thesis
    Open Access
    The aim of this Bachelor's Thesis is the study of a particular low-energy localized plane Poiseuille solution while minimizing the error introduced by the streamwise periodicity boundary condition. The fact that the ...
  • Computació de fluxos preturbulents bidimensionals al problema de Poiseuille pla 

    Rota Cunill, Joan (Universitat Politècnica de Catalunya, 2012-05-15)
    Minor thesis
    Open Access
    La inestabilitat dels fluxos i la transició a la turbulència són fenòmens estesos a l’enginyeria i el medi natural. El problema de Poiseuille és un dels escenaris típics en dinàmica de fluids on la transició de flux lamina ...
  • Digital control of pre-turbulent flows in a Taylor-Couette device 

    Gil Bofill, Núria (Universitat Politècnica de Catalunya, 2019-07-09)
    Bachelor thesis
    Open Access
    Transition to turbulence is one of the oldest problems yet to be solved in physics and engineering. Certain fluid systems are known to undergo a laminar-turbulent transition through a deterministic route of laminar flows ...
  • Large eddy simulation of the combustion in an oxygen-paraffin hybrid rocket engine 

    Homs Pons, Carme (Universitat Politècnica de Catalunya, 2019-06)
    Bachelor thesis
    Open Access
    Covenantee:  Zentrum für angewandte Raumfahrt­technologie und Mikro­gravitation
    En la última década se ha despertado un renovado interés en los cohetes híbridos debido a su bajo precio, manejo seguro y compatibilidad con carburantes verdes. Un grupo de estudiantes está desarrollando un cohete híbrido ...
  • Modelling the cardiovascular system: pulsating flow through a collapsible channel 

    Cabanes Bosacoma, Xavier (Universitat Politècnica de Catalunya, 2017-05)
    Bachelor thesis
    Open Access
    The interaction between fluid flows and the deformation of solid structures is important in many engineering applications, as in turbochargers, wind turbines or airplane wings. The flow of blood in the body is also an ...
  • Non-linear fluid dynamics in oscillatory cylindrical cavities 

    Panadès i Guinart, Carles (Universitat Politècnica de Catalunya, 2013-06-28)
    Doctoral thesis
    Open Access
    Even though the transition to turbulence has been studied for over a century, its complete comprehension still remains unclear even for the simplest flows and continues to be a daunting challenge for the scientific community. ...
