At the stages of maintenance and repair pipeline systems, there is a need to use flameless cutting in existing pipelines, particular: when it necessary connect intake chambers start cleaning pistons, during with complete replacement pipe body without stopping transportation product. Also, fireless effectively used branch pipelines development systems. One progressive directions improving method...

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...
