An analytical method for selecting the optimal nozzle external geometry for fluid dynamic gauging
(Elsevier, 2011-08)
Fluid dynamic gauging (FDG) was developed to measure, in situ and in real time, the thickness of a soft deposit layer immersed in a liquid without contacting the surface of the layer. An analysis based on the lubrication ...
Global analysis of aerodynamics deflectors efficiency in the grinding process
(2006-07-17)
The conventional, grinding methods in some cases are not very efficient because the arising of thermal damages in the pieces is very common. Optimization methods of cutting fluid application in the grinding zone are essential ...

Computation of solid-fluid-fluid equilibria for binary asymmetric mixtures in wide ranges of conditions
(Elsevier Science, 2011-05)
In this work, we propose and test a numerical continuation method (NCM) for calculating solid-fluid-fluid (SFF) equilibrium loci for binary asymmetric systems. Such loci generally exist over a wide range of conditions. The ...
Development of a supercritical fluid extraction method for simultaneous determination of organophosphorus, organohalogen, organonitrogen and pyretroids pesticides in fruit and vegetables and its comparison with a conventional method by GC-ECD and GC-MS
(2005-09-01)
The aim of this paper was to apply a multiresidue method using Supercritical Fluid Extraction (SFE) and capillary gas chromatography with electron capture and mass spectrometry detections in the analysis of the levels of ...

Multiresidue analysis of pesticides in soil by supercritical fluid extraction/gas chromatography with electron-capture detection and confirmation by gas chromatography-mass spectrometry
(Amer Chemical Soc, 2005-01-12)
The applicability of supercritical fluid extraction (SFE) in pesticide multiresidue analysis (organohalogen, organonitrogen, organophosphorus, and pyrethroid) in soil samples was investigated. Fortification experiments ...

A sustainable alternative for cooling the machining processes using a refrigerant fluid in recirculation inside the toolholder
(Springer, 2011-12-01)
This article presents a cooling system for cutting tool in turning based in a toolholder with cooling fluid flowing inside its body being that this fluid must necessarily be able to phase change due to heat generated from ...
