      Bachelor thesis
      Restricted access - author's decision
      In the last decades there has been a growing interest to develop mi-croscale devices that can manipulate and transport relatively small volumes of fluids. These devices have applications in many areas of engineering, including ...

    • Formation of tip-vortices on triangular prismatic-shaped cliffs. Part 1: A wind tunnel study 

      Cochard, S.; Letchford, C.W.; Earl, T. A.; Villardi de Montlaur, Adeline de (2012)
      Article
      Restricted access - publisher's policy
      Speed-up over topography has long been recognized as significant for structural design and wind energy applications. Here wind flow over cliffs that have a sawtooth plan are studied for speed-up effects under different ...

    • Granular flow characterisation towards an enhanced bulk feeder selection 

      Torres Serra, Joel (Universitat Politècnica de Catalunya, 2021-02-26)
      Doctoral thesis
      Open Access
      In the packaging industry, a wide range of powders and bulk solids are handled in bagging equipment using different bulk feeding techniques. Quality of the packaging is critically affected by feeder performance, which is ...

    • Intermittency and multi-fractal velocimetry (IMFV) in Rayleigh-Taylor and convective flows 

      Tellez Alvarez, Jackson David; Malik, Nadeem; Vila, Teresa; Redondo Apraiz, José Manuel (2016)
      Conference report
      Restricted access - publisher's policy
      New descriptors to investigate mixing in multi-scale turbulence analysis and couple PIV Laser induced applications with Fractal analysis in Shock induced flows as well as in convective driven flows are discussed. The ...

    • Magnetic hyperthermia for particle image velocimetry (MH-PIV) 

      Arias Montenegro, Francisco Javier; Heras Jiménez, Salvador Augusto de las (2021-01-26)
      Research report
      Open Access
      In this work a novel approach is investigated for Particle Image Velocimetry (PIV) which is a technique used as optical method for instantaneous flow visualization. So far traditional PIV is based in the injection of small ...
