    Article
    Open Access
    The suspensions used in heavy vehicles often consist of several oil and two gas chambers. In order to perform an analytical study of the mass flow transferred between two gas chambers separated by a nozzle, and when ...
  • Tychonis: a model-based approach to define and search for geometric events in space 

    Llopis, Marcel; Soria Guerrero, Manel; Franch Gutiérrez, Javier (2021-02-24)
    Article
    Restricted access - publisher's policy
    Space missions need software in order to be aware of the occurrence of geometric events in different phases of their project lifecycle. However, current software packages that provide capabilities to search for geometric ...

    Miró Jané, Arnau; Soria Guerrero, Manel; Cajas García, Juan Carlos; Rodríguez Pérez, Ivette María; Moulinec, Charles (2021-06)
    Article
    Restricted access - publisher's policy
    This work is focused on exploring the flow and heat transfer capabilities for slotted and axisymmetric cavity configurations for synthetic impinging jets; the jet is enclosed between two isothermal parallel plates, impinging ...
  • A review of gas-surface interaction models for orbital aerodynamics applications 

    Livadiotti, Sabrina; Crisp, Nicholas H.; Roberts, Peter C.E; García-Almiñana, Daniel; Rodríguez Donaire, Silvia; Sureda Anfres, Miquel (2020-11)
    Article
    Restricted access - publisher's policy
    Renewed interest in Very Low Earth Orbits (VLEO) - i.e. altitudes below 450 km - has led to an increased demand for accurate environment characterisation and aerodynamic force prediction. While the former requires knowledge ...
  • In-orbit aerodynamic coefficient measurements using SOAR (Satellite for Orbital Aerodynamics Research) 

    Crisp, Nicholas H.; Roberts, Peter C.E; Livadiotti, Sabrina; García-Almiñana, Daniel; Rodríguez Donaire, Silvia; Sureda Anfres, Miquel (2021-03)
    Article
    Restricted access - publisher's policy
    The Satellite for Orbital Aerodynamics Research (SOAR) is a CubeSat mission, due to be launched in 2021, to investigate the interaction between different materials and the atmospheric flow regime in very low Earth orbits ...
  • Airplane vortices evolution near ground 

    Duro, Josep M; Bergadà Granyó, Josep Maria (Multidisciplinary Digital Publishing Institute, 2021-01-05)
    Article
    Open Access
    Airport traffic around the world has sharply increased over the years; as a result, airports need to be enlarged and the landing or taking off times between two consecutive airplanes must be reduced. To precisely determine ...
  • Analyzing the performance of a miniature 3D wind sensor for Mars 

    Domínguez Pumar, Manuel; Kowalski, Lukasz; Jiménez Serres, Vicente; Rodríguez Pérez, Ivette María; Soria Guerrero, Manel; Bermejo Broto, Sandra; Pons Nin, Joan (Multidisciplinary Digital Publishing Institute (MDPI), 2020-10-20)
    Article
    Open Access
    This paper analyzes the behavior of a miniature 3D wind sensor designed for Mars atmosphere. The sensor is a spherical structure of 10 mm diameter divided in four sectors. By setting all the sectors to constant temperature, ...
  • On the effects of the free-stream turbulence on the heat transfer from a sphere 

    Rodríguez Pérez, Ivette María; Lehmkuhl, Oriol; Soria Guerrero, Manel (2021-01)
    Article
    Restricted access - publisher's policy
    Free-stream turbulence is present in many engineering applications and is known to affect both bluffbody aerodynamics and heat transfer. In this work, its effects on the heat transfer and the near wake behind a sphere are ...
  • Aerodynamic study of the NASA’s X-43A hypersonic aircraft 

    Navó, Alex; Bergadà Granyó, Josep Maria (Multidisciplinary Digital Publishing Institute, 2020-11-19)
    Article
    Open Access
    A 2D aerodynamic study of the NASA’s X-43A hypersonic aircraft is developed using two different approaches. The first one is analytical and based on the resolution of the oblique shock wave and Prandtl–Meyer expansion wave ...
  • A Versatile Gripper for Cloth Manipulation 

    Donaire Cónsul, Sònia; Borràs Sol, Júlia; Alenyà Ribas, Guillem; Torras, Carme (Institute of Electrical and Electronics Engineers (IEEE), 2020-10)
    Article
