Characterization of silica–water nanofluids dispersed with an ultrasound probe: A study of their physical properties and stability
Mondragon, Rosa; Juliá Bolívar, José Enrique; Barba-Juan, Antonio; Jarque Fonfría, Juan Carlos Elsevier (2012)The stability and agglomeration state of nanofluids are key parameters for their use in different applications. Silica nanofluids were prepared by dispersing the nanoparticles in distilled water using an ultrasonic probe, ... -
Determination of the packing fraction of silica naoparticles from the rheological and viscoelastic measurements of nanofluids
Mondragon, Rosa; Juliá Bolívar, José Enrique; Barba-Juan, Antonio; Jarque Fonfría, Juan Carlos elsevier (2012-10)Nanofluids have become of great interest due to the excellent properties and reduced size of nanoparticles making them useful for different applications. The agglomeration of nanoparticles depends on the interparticle ... -
Effect of slurry properties and operational conditions on the structure and properties of porcelain tile granules dried in an acoustic levitator
Mondragon, Rosa; Jarque Fonfría, Juan Carlos; Juliá Bolívar, José Enrique; Hernandez, Leonor; Barba-Juan, Antonio Elsevier (2012)Spray-drying is a unit operation highly important in many industrial applications. In this work, the influence of the drying conditions on the final grain properties has been investigated in single droplet experiments.Porcelain ... -

Mondragon, Rosa; Juliá Bolívar, José Enrique; Hernandez, Leonor; Jarque Fonfría, Juan Carlos Taylor & Francis (2013-05-03)The particle size of the primary particles is an important parameter influencing the drying behavior of droplets. In this work, the influence of particle size on the drying kinetics and grain properties was analyzed for ... -
Influence of the particle size on the microstructure and mechanical properties of grains containing mixtures of nanoparticles and microparticles: Levitator tests and pilot-scaled validation
Mondragon, Rosa; Juliá Bolívar, José Enrique; Barba-Juan, Antonio; Jarque Fonfría, Juan Carlos Elsevier (2013)The spray drying process is used in many industrial applications. However, different grain properties can be desirable depending on the later use of the powders produced. In this work the influence of the particle size on ... -
Modeling of Drying Curves of Silica Nanofluid Droplets Dried in an Acoustic Levitator Using the Reaction Engineering Approach (REA) Model
Mondragon, Rosa; Juliá Bolívar, José Enrique; Hernandez, Leonor; Jarque Fonfría, Juan Carlos Taylor & Francis (2013)The use of nanoparticles has become of great interest in different industrial applications. The spray drying of nanofluids forms nanostructured grains, preserving the nanoparticle properties. In this work, individual ... -
El proceso de secado por atomización: formación de gránulos y cinética de secado de gotas
Mondragon, Rosa; Juliá Bolívar, José Enrique; Barba-Juan, Antonio; Jarque Fonfría, Juan Carlos Sociedad Española de Cerámica y Vídrio (2013-07)Spray drying is a unit operation very common in many industrial processes. For each particular application, the resulting granulated material must possess determined properties that depend on the conditions in which the ...
