Measurement of electric potential of isolated vertical conductive wires pulled by a drone under fair weather conditions
(2018)
Conference lecture
Restricted access - publisher's policyThe popularization of multicopter drones opens new possibilities for investigations of the atmospheric potential. The method of directly measuring of the electric potential drop of the lower part of the atmosphere has been ... -
Preliminary assessment of a polygeneration system based on a concentrated photovoltaic thermal (CPVT) solar collectors
(Technishe Universität Berlin, 2021)
Conference report
Open AccessECOSun project has as main objective a cost reduction of electricity and heat co-generation via a Concentrated Photovoltaic/Thermal (CPV-T) system by applying low-cost materials and advanced industrial manufacturing methods. ... -
Surface tension and contact angle measurement of LiBr and Carrol solution
(Technishe Universität Berlin, 2021)
Conference report
Open AccessThe surface tension and contact angle play a relevant role in the heat and mass transfer for the absorption system working pairs. However, LiBr aqueous solution surface tension/contact angle studies are limited and for ... -
Weaving communities, the missing link for the social impact of universities: using network analysis to study the formation of communities at the UPC
(Global University Network for Innovation, 2020)
Conference lecture
Restricted access - publisher's policyCollaboration between and among organizations is one of the key elements in their sustainability and resiliency (Capra, 2002). One of the most effective ways to enhance collaboration, especially in those areas concerning ... -
Energy preserving multiphase flows: applications to falling films
(2021)
Conference report
Open AccessThe numerical simulation of multiphase flows presents several challenges, namely the transport of different phases within de domain and the inclusion of capillary effects. Here, these are approached by enforcing a discrete ... -
Measurement of the Influence of Sheet Cavitation on the Heat Generated in a Closed Loop Pumping System
(2021)
Conference lecture
Restricted access - publisher's policyThe so-called hydrodynamic heat generators are claimed as high efficiency heating devices, avoiding scaling by warming liquids without transfer surface with the help of cavitation effects. However, neither the mechanisms ... -
Effect of land cover and climate changes on rainfall-induced landslides: regional-scale modelling in the Val d’Aran (Pyrenees, Spain)
(International Society for Soil Mechanics and Geotechnical Engineering (ISSMGE), 2021)
Conference report
Open AccessThe analysis of the impacts of future environmental changes on rainfall-induced landslides is of great importance. Recent studies have shown that these changes will affect the frequency and magnitude of shallow slides and ... -
Effect of the actuation on the boundary layer of an airfoil at moderate reynolds number
(Springer, 2020)
Conference report
Restricted access - publisher's policySynthetic (zero net mass flux) jets are an active flow control technique to manipulate the flow field in wall-bounded and free-shear flows. The fluid necessary to actuate on the boundary layer is intermittently injected ... -
Wakes and instabilities of static and freely vibrating cylinders
(Springer, 2019)
Conference report
Open AccessThe flow around static and freely vibrating cylinders are of interest in understanding different phenomena encountered in many practical applications. -
Assessment of LES techniques for mitigating the Grey Area in DDES models
(2019)
Conference report
Open AccessThe slow RANS-LES transition is a well-known shortcoming in hybrid turbulence models such as DelayedDetached Eddy Simulation (DDES). The present work assesses the feasibility of 2D sensitive LES models for naturally ... -
Improving DES capabilities for predicting Kelvin-Helmholtz instabilities. Comparison with a backward-facing step DNS.
(2020-05-10)
Conference report
Restricted access - publisher's policyThe Detached Eddy Simulation (DES) turbulence model presented by Spalart et al. (Comments on the Feasibility of LES for Wings, and on a Hybrid RANS/LES Approach, [1]) in the late 90s, was specifically designed to simulate ... -
Exploring the performance of a miniature 3D wind sensor under extreme martian winds up to the dust devil scale
(2019)
Conference report
Open AccessThe objective of this paper is to explore the performance of a miniature 3D spherical wind sensor for Mars atmosphere, working under extreme wind speeds, up to the Dust Devil scale. The experimental campaign has been made ...
