The objective of this paper is to study the feasibility of large eddy simulations of a liquid fuel injection in combustion chambers. To do so, a priori analyses of direct numerical simulations are carried out. A complete liquid jet atomization, from the injector down to the end of the liquid core, is simulated thanks to the coupling of both level-set and VOF formulations. To avoid the apparitio...

Supercritical Assisted Atomization (SAA) has been used to micronize α-cyclodextrin (α-CD) and hydroxypropyl-β-cyclodextrin (HP-β-CD). The effect of some process parameters such as precipitation temperature and solute concentration in the liquid solution has been studied to evaluate their influence on morphology and size of precipitated particles. Cyclodextrins micronization has been obtained wi...

This paper investigates the primary atomization of airblasted liquid sheet using detailed numerical simulations. The under airblasting conditions involve complex mechanisms and a thorough understanding is necessary. A planar pre-filming airblast configuration have been chosen to study breakup sheet/film injected on solid flat plate. We investigated an operating point directly relevant for high ...

• Oral drug delivery systems were prepared by single step co-axial electrohydrodynamic atomization with high processing yield. • Polymer carrier systems (PCS) suitable for the process and drugs were developed first. • Model drugs of different aqueous solubility were successfully incorporated in the PCS with 50-70% encapsulation efficiency. • This technique is a versatile platform for combined d...

We here propose a polynomial-time deterministic finite automaton minimization algorithm directly derived from Brzozowski’s double reversal algorithm. To do so, we take into account the framework by Brzozowski and Tamm, to propose an atomization algorithm that allows us to achieve polynomial time complexity. © 2013 Elsevier B.V.

The atomization of turbulent liquid jets and sheets can usually be divided into two subsequent processes: the primary breakup, where the jet or sheet initially breaks up into both large and small scale structures, followed by the secondary breakup, where these structures continue to break up into ever smaller drops, forming a spray. Considering numerical grid resolutions typical for Large Eddy ...
