  • Energy-consistent discretization of viscous dissipation with application to natural convection flow 

    Sanderse, Benjamin; Trias Miquel, Francesc Xavier (Elsevier, 2025-01-15)
    Article
    Open Access
    A new energy-consistent discretization of the viscous dissipation function in incompressible flows is proposed. It is implied by choosing a discretization of the diffusive terms and a discretization of the local kinetic ...

  • Thermal analysis of an integrated motor drive with a switching cell array power converter 

    Grespan, Mattia; Busquets Monge, Sergio; Mas de les Valls Ortiz, Elisabet; Jordà Sanuy, Xavier; Raya di Francisco, Mariana Candela; Angeli, Diego
    Conference report
    Open Access
    In modern electric propulsion systems the electric motor is tightly integrated with the power converter and control unit. These so called Integrated Motor Drives can allow for vast improvements in efficiency and volume ...

  • Absenteeism in maritime education: insights, challenges, and innovative solutions 

    Castells Sanabra, Marcel·la; Mas de les Valls Ortiz, Elisabet; Barahona Fuentes, Claudia; Borén Altés, Clara; Fernández Canti, Rosa M.; Mujal Colilles, Anna (Massachusetts Maritime Academy, 2024)
    Conference report
    Open Access
    Students’ attendance at classes is a measure that reflects students’ enthusiasm for the course and their status in the university. University-level absenteeism is influenced by various factors, ranging from academic ...
