A locally extended finite element method for the simulation of multi-fluid flows using the Particle Level Set method
(2015-09)
Article
Accés obertThe simulation of immiscible two-phase flows on Eulerian meshes requires the use of special techniques to guarantee a sharp definition of the evolving fluid interface. This work describes the combination of two distinct ... -
An acoustic technique for propellant gauging
(2022)
Text en actes de congrés
Accés restringit per política de l'editorialThe 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 ... -
Analysis of two-phase flows under microgravity (spatial) conditions using OpenFOAM
(Universitat Politècnica de Catalunya, 2020-07-23)
Treball Final de Grau
Accés obertTwo-phase flows have gained importance over the last years due to their multiple and useful applications in space systems. For example, two-phase flows are used in fuel cells micro-channel networks, in the fluid management ... -
