Theoretical Relation Between the Tube Zeta Potential and the Background Electrolyte Composition in Capillary Electrophoresis
(Springer, 2004-08)
This work presents a theoretical analysis of the relation between the tube zeta potential and the electrolyte solution composition typically found in capillary electrophoresis. A model including the relevant physicochemical ...
Numerical analysis of refrigerant flow along non-adiabatic capillary tubes using a two-fluid model
(Pergamon-Elsevier B.V. Ltd, 2009-02-01)
This work presents a numerical model to simulate steady state refrigerant now along capillary tube-suction line heat exchangers. commonly used in small refrigeration systems. The flow along the straight and horizontal ...
A two-fluid model for refrigerant flow through adiabatic capillary tubes
(Abcm Brazilian Soc Mechanical Sciences & Engineering, 2014-01-01)
This work presents a numerical model to simulate refrigerant flow through capillary tubes, commonly used as expansion devices in refrigeration systems. The flow is divided in a single-phase region, where the refrigerant ...
Experimental evaluation on the oil influence in capillary tubes
(PERGAMON-ELSEVIER SCIENCE LTD, 2009)
This work presents the results of an experimental study on pure refrigerant R-134a and refrigerant-oil mixtures flowing through capillary tubes in order to analyse the oil influence in component performance. Tests were ...
Análise do escoamento de HFC-134a em tubos capilares usando o modelo de dois fluidos
(1996-03-01)
This work presents a numerical model to simulate refrigerant flow through capillary tubes, commonly used as expansion devices in refrigeration systems. The capillary tube is considered straight and horizontal. The flow is ...
Asymmetric capillary filling of non-Newtonian power law fluids
(Springer, 2014-03)
A theoretical analysis of the capillary-driven imbibitions of non-Newtonian fluids in conical capillaries is presented. More precisely, the consequences of the variation in the fluid viscosity with the shear rate are ...
The stability of the steady motion of a liquid plug in a capillary tube
(American Chemical Society, 2007-12)
In this work, we present a methodology to analyze the stability of the steady-state propagation of a liquid plug in a capillary tube lined with a uniform film of the same liquid. To this end, the steady-state solutions are ...
Determination of fluoxetine and norfluoxetine enantiomers in human plasma by polypyrrole-coated capillary in-tube solid-phase microextraction coupled with liquid chromatography-fluorescence detection
(ELSEVIER SCIENCE BV, 2009)
A sensitive, selective, and reproducible in-tube polypyrrole-coated capillary (PPY) solid-phase microextraction and liquid chromatographic method for fluoxetine and norfluoxetine enantiomers analysis in plasma samples has ...
Dynamic model and experimental study of an air-water heat pump for residential use
(Elsevier Sci LtdOxfordInglaterra, 2013)
New method for sintering silica frits for capillary microcolumns
(Elsevier Science, 2014-04)
One of the main steps in the manufacture of robust and efficient packed capillary microcolumns for electro- and capillary chromatography is the generation of porous devices to retain the packed beds. Frits based on sintered ...
