Buoyancy and capillary effects on floating liquid lenses
(American Physical Society, 2020-07)
We study the equilibrium shape of a liquid drop resting on top of a liquid surface, i.e., a floating lens. We consider the surface tension forces in nonwetting situations (negative spreading factor), as well as the effects ...
New prediction methods for CO2 evaporation inside tubes: Part I - A two-phase flow pattern map and a flow pattern based phenomenological model for two-phase flow frictional pressure drops
(PERGAMON-ELSEVIER SCIENCE LTD, 2008)
An updated flow pattern map was developed for CO2 on the basis of the previous Cheng-Ribatski-Wojtan-Thome CO2 flow pattern map [1,2] to extend the flow pattern map to a wider range of conditions. A new annular flow to ...

Two-phase flow frictional pressure drop prediction in helical coiled tubes
(Pergamon-Elsevier Science Ltd, 2020-12)
Based on the construction of different experimental databases, the frictional pressure drop in helical tubes for single-phase and water-steam two-phase flow was analyzed empirically. The aim of the present study is to ...
Numerical investigation of three dimensional viscoelastic free surface flows: impacting drop problem
(International Association for Computational Mechanics (IACM)European Community on Computational Methods in Applied Sciences (ECCOMAS)Barcelona, 2014-07-20)
This work presents a numerical investigation of three dimensional viscoelastic
free surface flows. In particular, using two different numerical methodologies, we have
simulated a typical free-surface benchmark flow ...
Pressure drop correlation for oil-refrigerant R134a mixture flashing flow in a small diameter tube
(Elsevier B.V., 2009-05-01)
This paper presents an experimental investigation of the ester oil ISO VG10/refrigerant R134a mixture flashing flow in a 6.0 m long, 3.22 mm ID tube, which is one of the primary steps towards the construction of a methodology ...

A combination of single-drop microextraction and open tubular capillary electrochromatography with carbon nanotubes as stationary phase for the determination of low concentration of illicit drugs in horse urine
(Elsevier Science, 2011-10-16)
In this study we developed an interesting alternative to HPLC-mass spectrometry for the quantification of seven important drugs of abuse in racehorses. The procedure proposed in this work is a combination of single-drop ...
