  • Fractal rigidity of the wheel-rail contact 

    Babici, Laura Mariana; Tudor, Andrei; Romeu Garbí, Jordi; Stoica, M. (Institute of Physics (IOP), 2020-12-25)
    Article
    Open Access
    One of the essential parameters of the roughness with effects on the vibration of the wheel and the rail is the contact stiffness. This rigidity considers the geometry and material of the wheel and rail, which are considered ...
  • Flow control in porous media: from numerical analysis to quantitative µPAD for ionic strength measurements 

    Mehrdel, Pouya; Khosravi, Hamid; Karimi, Shadi; López Martínez, Joan Antoni; Casals Terré, Jasmina (Multidisciplinary Digital Publishing Institute (MDPI), 2021-05-11)
    Article
    Open Access
    Microfluidic paper-based analytical devices (µPADs) are a promising technology to enable accurate and quantitative in situ assays. Paper’s inherent hydrophilicity drives the fluids without the need for external pressure ...
  • Increasing the operating range and energy production in Francis turbines by an early detection of the overload instability 

    Zhao, Weiqiang; Presas Batlló, Alexandre; Egusquiza Montagut, Mònica; Valentín Ruiz, David; Egusquiza Estévez, Eduard; Valero Ferrando, Ma. del Carmen (2021-08)
    Article
    Open Access
    With the increasing entrance of wind and solar power for the generation of electricity, more flexibility is demanded to hydropower plants. More flexibility means that hydro turbines have to increase the operating range ...
  • Simulation of ejector for vacuum generation 

    Macià Cid, Llorenç; Castilla López, Roberto; Gámez Montero, Pedro Javier (Institute of Physics (IOP), 2019-10-31)
    Article
    Open Access
    Supersonic ejectors are used in a wide range of applications such as compression of refrigerants in cooling systems, pumping of volatile fluids, or vacuum generation. The objective of the present paper is to mesh and ...

    Article
    Open Access
    The work provides an exhaustive comparison of some representative families of topology optimization methods for 3D structural optimization, such as the Solid Isotropic Material with Penalization (SIMP), the Level-set, the ...
  • The surface modification of boron nitride particles 

    Daneshmehr, Shahla; Román Concha, Frida Rosario; Hutchinson, John M. (Springer, 2019-01-01)
    Article
    Open Access
    The use of coupling agents to enhance the thermal conductivity of composites of epoxy and boron nitride (BN) has been investigated. Two types of BN particles, lightly aggregated platelets with an average size of 6 µm and ...
  • Active flow control optimisation on SD7003 airfoil at pre and post-stall angles of attack using synthetic jets
