Experimental investigation of the impact of single droplets of non-Newtonian fluid
(Universitat Politècnica de Catalunya / Technishe Universität Darmstadt, 2009)
Master thesis (pre-Bologna period)
Restricted access - author's decisionThis study is devoted to the investigation of impact of a paint drop onto a thin liquid film. In particular the mechanism of bubble entrapment during drop impact will be studied. The study is motivated by the technology ... -
Experimental study of diphasic flow during the injection stage of composite processing
(Universitat Politècnica de Catalunya, 2019-04-24)
Bachelor thesis
Open Access
Covenantee: École polytechnique de MontréalThe bubbles have been studied for 20 years. In the aeronautical sector, these bubbles appear during the injection for the creation in a composite material when the air is entrapped. For an aeronautical part certification, ... -
Gravity-driven motion of a swarm of bubbles in a vertical pipe

(Elsevier, 2019-06-15)
Article
Open AccessThis paper focuses on three-dimensional direct numerical simulations of rising bubbles in the wobbling regime, and the study of its dynamical behavior for Eötvös number 1 ≤ Eo ≤ 10 and Morton number 1e−11 ≤ M ≤ 1e−9. ... -
Numerical study with OpenFOAM of the bubble generation process in an inverse T-junction in microgravity conditions
(Universitat Politècnica de Catalunya, 2019-07-16)
Bachelor thesis
Open AccessMicrogravity is the condition perceived in an object or body when gravity effect is negligible. This can mostly happen when the object is in a constant free fall state, which gives the false perception of Zero Gravity. It ... -
