  • Multidisciplinary numerical analysis of detonation engines 

    Hernandez Castro, Francisco Javier (Universitat Politècnica de Catalunya, 2019-01-10)
    Master thesis
    Restricted access - author's decision
    Covenantee:  Von Karman Institute for Fluid dynamics
    The performance of pulse detonation engines (PDE) implies that they have to undergo very extreme cycles where the temperature may rise above 3000 K. The detonation principle, theoretically predicted by the ZND condition, ...

    Samala, Bhanu Prakash Reddy (Universitat Politècnica de Catalunya, 2015-06-16)
    Master thesis
    Open Access
    Objectives: The major objective of the Master Thesis proposal is to perform 2D computational study and compare the enhancement in the global aerodynamic coefficients, mainly lift and drag coefficients, for cases of with ...
  • Numerical study and optimization of a GT car Rear-Wing aerodynamics 

    Arianezhad, Masoud (Universitat Politècnica de Catalunya, 2015-03-26)
    Master thesis
    Open Access
    The same principle that allows an airplane to rise off the ground by creating lift from its wings is used upside-down to generate the downforce that pushes a race car against the surface of the track. This effect is sometimes ...
  • Numerical study on aerodynamic drag reduction of passenger cars 

    Sanchez Martinez, Javier (Universitat Politècnica de Catalunya, 2015-09-30)
    Bachelor thesis
    Open Access
    The scope of this work is to identify potential improvements on Passenger cars Aerodynimcs (Drag reduction and Downforce increase) to help to minimize fuel consumption and hence reduce exhaust emisions. The Ahmed body ...
