Numerical and experimental characterization of the hydrodynamics and drying kinetics of a barbotine slurry spray
Sebastia-Saez, Daniel; Hernandez, Leonor; Arellano-Garcia, Harvey; Juliá Bolívar, José Enrique Elsevier (2019-02-23)Spray drying is a basic unit operation in several process industries such as food, pharmaceutical, ceramic, and others. In this work, a Eulerian-Lagrangian three-phase simulation is presented to study the drying process ... -
Numerical Modeling of the Mechanical Reliability of Multicoated Nanoencapsulated Phase-Change Materials with Improved Thermal Performance
Forner Escrig, Josep; Navarrete Argilés, Nuria; Palma Guerrero, Roberto; La Zara, Damiano; Goulas, Aristeidis; Valdesueiro, David; van Ommen, J. Ruud; Hernandez, Leonor; Mondragon, Rosa Wiley (2021-12-21)Nanoencapsulated phase-change materials (nePCMs) are investigated for enhancing thermal energy storage. However, the shell of these nanocapsules may fail due to stress developed during thermal processes, leading to melting ... -
On the use of area-averaged void fraction and local bubble chord length entropies as two- phase flow regime indicators
Hernandez, Leonor; Juliá Bolívar, José Enrique; Paranjape, Sidharth; Hibiki, Takashi; Ishii, M. Springer Verlag (2010)In this work, the use of the area-averaged void fraction and bubble chord length entropies is introduced as flow regime indicators in two-phase flow systems. The entropy provides quantitative information about the disorder ... -
Optical characterisation and photothermal conversion efficiency of a water-based carbon nanofluid for direct solar absorption applications.
Gimeno Furió, Alexandra; Martinez Cuenca, Raul; Mondragon, Rosa; VELA GASULLA, ANTONIO FABIAN; Doñate-Buendía, Carlos; Mínguez-Vega, Gladys; Hernandez, Leonor Elsevier (2020-12-01)Carbon nanoparticles are very useful in solar thermal applications as they absorb much of the solar spectrum and can be inexpensive. Water-based carbon nanofluids with two different concentrations (3 and 33 mg l−1) were ... -
Optical characterisation of oxidised carbon nanohorn nanofluids for direct solar energy absorption applications
Gimeno Furió, Alexandra; Hernandez, Leonor; Barison, Simona; Agresti, Filippo; Cabaleiro, David; mancin, simone Elsevier (2019-10-31)Carbon nanohorns and oxidised carbon nanohorns-based nanofluids were characterised by taking one step forward. The advantage of studying oxidised carbon nanohorns is that they are surfactant-free. The stability of both ... -
Photothermal properties and performance of hybrid carbon-paraffin/water emulsions
Burgos Rodríguez, Jorge; Mondragon, Rosa; Martinez Cuenca, Raul; Udayashankar, Nithiyanantham; Barison, Simona; mancin, simone; Fabregat-Santiago, Francisco; Hernandez, Leonor Elsevier (2023-10-09)Solar thermal energy has attracted renewed research interest for its excellent energy efficiency among different types of solar technologies. However, the limiting factor of them all is the intermittent nature of solar ... -
