A negative reactivity feedback driven by induced buoyancy after a temperature transient in lead-cooled fast reactors
(2017-10-24)
Article
Accés obertConsideration is given to the possibility to use changes in buoyancy as a negative reactivity feedback mechanism during temperature transients in heavy liquid metal fast reactors (HLMFRs). It is shown that by the proper ... -
New subgrid-scale models for large-eddy simulation of Rayleigh-Bénard convection
(Institute of Physics (IOP), 2016)
Text en actes de congrés
Accés obertAt the crossroad between flow topology analysis and the theory of turbulence, a new eddy-viscosity model for Large-eddy simulation has been recently proposed by Trias et al.[PoF, 27, 065103 (2015)]. The S3PQR-model has the ... -
On inflatable drones for flight time enhancement with particular reference to spectator aerostation
(2018-08-30)
Report de recerca
Accés obertIn this note consideration is given to drones - and specially quadcopters, endowed with inflatable and controllable airbags filled with helium which is stored in small and replaceable cartridges. The goal is the a flight ... -
On the use of a dedicated ballast pellet for a prompt self-ejection mechanism after a temperature transient in lead-cooled fast reactors
(2017-10)
Article
Accés obertThe potential use of changes in buoyancy as a reactivity feedback mechanism during temperature transients in heavy liquid metal fast reactors (HLMFRs) is discussed. It is shown that with the use of ballast pellets (~15% ... -
Pool pressure-retarded osmosis
(2020-04-23)
Article
Accés obertIn this work, consideration is given for pressure-retarded osmosis (PRO) system in a pool configuration. The motivation behind of such a configuration lies in the possibility to eliminate mechanical moving parts or energy ... -
Semianalytical solution for CO2 plume shape and pressure evolution during CO2 injection in deep saline formations
(2013-01-16)
Article
Accés restringit per política de l'editorialThe injection of supercritical carbon dioxide (CO2) in deep saline aquifers leads to the formation of a CO2 rich phase plume that tends to float over the resident brine. As pressure builds up, CO2 density will increase ... -
Solar thermal panels for small-medium scale air cleaners in major cities
(2019-03-01)
Article
Accés obertAir quality in major cities is reaching worrisome levels across the planet owing to large-scale industrialization. As a result, air purification systems are becoming a fertile and emerging field for research. Here, ...
