A mathematical model of spray drying granulation process in formulation

Kagami, Hiroyuki (Editorial Universitat Politècnica de València, 2018-09-07)

[EN] In this study, we apply the drying model of polymer solution coated on a flat substrate to the spray drying granulation process in formulation. In order to apply the former model to the drying of this spherical object, ...
A model for mono- and multi-component droplet heating and evaporation and its implementation into ANSYS Fluent

Poulton, Luke; Rybdylova, Oyuna; Sazhin, Sergei S.; Crua, Cyril; Qubeissi, Mansour; Elwardany, Ahmed E. (Editorial Universitat Politècnica de València, 2017-07-28)

[EN] A model for heating and evaporation of mono- and multi-component droplets, based on analytical solutions to the heat transfer and species diffusion equations in the liquid phase, is summarised. The implementation of ...
A new approach to modelling the two way coupling for momentum transfer in a hollow-cone spray

Papoutsakis, Andreas; Sazhin, Sergei; Begg, Steven; Danaila, Ionut; Luddens, Francky (Editorial Universitat Politècnica de València, 2017-07-28)

[EN] A new approach to modelling the interaction between droplets and the carrier phase is suggested. The new model is applied to the analysis of a spray injected into a chamber of quiescent air, using an Eulerian-Lagrangian ...
Coating effect of micro-sized droplets impacting on low temperature spherical particles

Wu, Xiusheng; Ma, Xiaoyu; Xu, Qing; Li, Zhanyong; Wang, Ruifang (Editorial Universitat Politècnica de València, 2018-09-07)

[EN] In this paper, the effect of spray droplets on the coating of cold spherical particles was studied.The microcapsule granulator produces micron-sized droplets to coat the spherical particles in cold storage, and the ...
Development steps of 2-color laser-induced fluorescence with MDR-enhanced energy transfer for instantaneous planar temperature measurement of micro-droplets and sprays

Palmer, Johannes; Reddemann, Manuel; Kirsch, Valeri; Kneer, Reinhold (Editorial Universitat Politècnica de València, 2017-07-28)

[EN] A new method for instantaneous measurement of temperature, size and velocity of micro-droplets has been developed. The method is based on the well-known 2-color laser-induced fluorescence (2cLIF) technique, but uses a ...
Kinetic and MD modelling of automotive fuel droplets heating and evaporation: recent results

Sazhin, Sergei; Shishkova, Irina (Editorial Universitat Politècnica de València, 2017-07-28)

[EN] Recent results of the investigation of kinetic and molecular dynamics (MD) models for automotive fuel droplet heating and evaporation are summarised. The kinetic model is based on the consideration of the kinetic ...
LARGE EDDY SIMULATION FOR THE PREDICTION OF HUMAN COUGHING

Payri, Raul; Marti-Aldaravi, Pedro; Quintero-Igeño, Pedro-Manuel; Marco-Gimeno, Javier (Begell House Inc., 2021)

[EN] The health awareness that has arisen from the COVID pandemic has been translated into interest in studying the contagion methods of airborne viruses. The cough mechanism is one cause of virion spread. To analyze this ...
Silicon nanoparticles as Raman scattering enhancers

Rodríguez, Marie-Isabelle; Shi, Lei; Lu, Xiaotang; Korgel, Brian; Alvarez -Puebla, Ramon; Meseguer Rico, Francisco Javier (Royal Society of Chemistry, 2014-06-07)

[EN] In this communication we demonstrate the large amplification values of the Raman signal of organic molecules attached to silicon nanoparticles (SiNPs). Light induced Mie resonances of high refractive index particles ...
The effect of surface texture on water droplet rebound on superhydrophobic surfaces

Piñero Bitriaga, Airoha Silmar (Universitat Politècnica de València, 2023-09-19)

[ES] Las superficies superhidrofóbicas muestran baja afinidad hacia el agua debido a la captura de aire en las asperezas de la superficie, lo que resulta en un ángulo de contacto alto superior a 150° y un ángulo de rodadura ...
