  • Optimization of synthetic jet actuation on a SD7003 airfoil in stall conditions 

    Monshi Tousi, Navid; El Mansy, Reda; Mellibovsky Elstein, Fernando; Bergadà Granyó, Josep Maria (2022)
    Conference report
    Open Access
    We optimise a set of Synthetic Jet (SJ) Active Flow Control (AFC) parameters on a SD7003 airfoil in order to maximise lift and aerodynamic efficiency. 2D-RANS with the Spallart Almaras (SA) turbulence model is employed in ...

  • An acoustic technique for propellant gauging 

    Fili, Thomas; Quintana Buil, Guillem; González Cinca, Ricardo (2022)
    Conference report
    Restricted access - publisher's policy
    The gauging of propellants in upper stages or satellites in orbit is a challenging task due to the absence of buoyancy, which makes liquids and gases adopt a large variety of configurations. The new Spectral Mass Gauging ...

  • Heat transfer management in propellant tanks 

    Quintana Buil, Guillem; González Cinca, Ricardo (2022)
    Conference report
    Restricted access - publisher's policy
    A critical issue in long-term space exploration missions is the storage and management of cryogenic propellants. Storage tanks are exposed to extreme temperatures and radiation, and hot spots might appear on the tank walls ...

  • Integrated acoustic technology for boil-off control, mass gauging, and structural health monitoring in cryogenic fuel tanks 

    Quintana Buil, Guillem; Abecia Hernanz, Sara Cecilia; Mangram, William; Khasin, Michael; Chang, Fu Kuo; González Cinca, Ricardo (2022)
    Conference report
    Restricted access - publisher's policy
    Long-term space exploration missions require efficient systems for cryogenic propellant storage and management. The exposure of the fuel tanks to the in-space operational environment implies the need for efficient technologies ...

  • Square cylinder downstream of two different-velocity streams 

    El Mansy, Reda; Monshi Tousi, Navid; Bergadà Granyó, Josep Maria; Mellibovsky Elstein, Fernando (2022)
    Conference lecture
    Open Access
    We study the flow past a square cylinder immersed in the wake of an upstream splitter plate separating two different-velocity streams. The bottom stream Reynolds number, ReB = 56 is kept constant for all cases, while the ...

  • Study of the conservation properties in two-way coupled dispersed multiphase flows using finite volume methods 

    Bahramian, Linda; Muela Castro, Jordi; Pérez Segarra, Carlos David (Institute of Physics (IOP), 2021)
    Conference lecture
    Open Access
    In order to simulate dispersed multiphase flows, the coupling level must be determined according to the volume fraction in the system. The volume fraction is the ratio of the total volume of the dispersed phases over the ...

  • Análisis multivariante de los factores determinantes en el cálculo del periodo fundamental de edificios 

    Caselles Magallón, Josep Oriol; Espinoza Barreras, Fortunato; Pujades Beneit, Lluís; Canas Torres, José Antonio; Navarro Bernal, Manuel; Lana Pons, Francisco Javier (AIBIS, 2001)
    Conference report
    Open Access
    La importancia de conocer posibles efectos de resonancia e interacción suelo­estructura conlleva la necesidad de métodos de cálculo del periodo fundamental de las estructuras y los periodos propios del suelo. La utilización ...

  • GPS and Galileo Wide Area RTK concepts 

    Hernández Pajares, Manuel; Juan Zornoza, José Miguel; Sanz Subirana, Jaume; Garcia Rodriguez, Alberto (Institut de Geomàtica, 2005)
    Conference report
    Open Access

  • Preliminary NeQuick assessment for future single frequency users of GALILEO 

    Aragón Ángel, María Ángeles; Orús Pérez, Raül; Hernández Pajares, Manuel; Juan Zornoza, José Miguel; Sanz Subirana, Jaume (2005)
    Conference report
    Open Access
    The NeQuick model is the ionospheric mo del that will be used by the GALILEO single frequency user to compute ionospheric corrections. In this framework, the aim of this study is to show a preliminary assessment of the ...

  • On the Interpolation Problem for the Poisson Equation on Collocated Meshes 

    Santos Serrano, Daniel; Muela Castro, Jordi; Valle Marchante, Nicolás; Trias Miquel, Francesc Xavier (International Centre for Numerical Methods in Engineering (CIMNE), 2021)
    Conference report
    Open Access
    The appearence of unphysical velocities in highly distorted meshes is a common problem in many simulations. In collocated meshes, this problem arises from the interpolation of the pressure gradient from faces to cells. ...

  • Effects of an imposed axial flow on a ferrofluidic Taylor-Couette flow 

    Altmeyer, Sebastian Andreas; Do, Younghae (2021)
    Conference report
    Open Access
    We investigate the effects of an externally imposed axial mass flux [1, 2] (axial pressure gradient, axial through flow) on ferrofluidic Taylor-Couette flow under the influence of either an axial or a transverse magnetic ...

  • BIBLOS for simulation of the Earth observation missions 

    Kedzierawski, Robert; Oryszczak, Wojciech; Szczepankiewicz, Karolina; Camps Carmona, Adriano José; Hyuk, Park; Barrios García, Pedro A. (International Society for Photo-Optical Instrumentation Engineers (SPIE), 2019)
    Conference report
    Restricted access - publisher's policy
    End-to-End Mission Performance Simulators for Earth Observation missions are one of the prominent tools for system design and scientific validation in early mission phases. The European Space Agency has promoted efforts ...
