Carbon dioxide evaporation in a single microchannel
Despite its importance for designing evaporators and condensers, a review of the literature shows that heat transfer data during phase change of carbon dioxide is very limited, mainly for microchannel flows. In order to ...
Flow boiling heat transfer of R134a and R245fa in a 2.3 mm tube
(PERGAMON-ELSEVIER SCIENCE LTD, 2010)
This paper presents new experimental flow boiling heat transfer results in micro-scale tubes. The experimental data were obtained in a horizontal 2.3 mm I.D stainless steel tube with heating length of 464 mm, R134a and ...
The effect of a perpendicular and cumulative inlet flow on the mass-transfer distribution in parallel-plate electrochemical reactors
A perpendicular inlet flow of electrolyte is analysed as a means of improving mass-transfer in a parallel-plate electrochemical reactor. Experimental local Sherwood numbers along the electrode length are reported for ...

New prediction methods for CO2 evaporation inside tubes: Part II - An updated general flow boiling heat transfer model based on flow patterns
(PERGAMON-ELSEVIER SCIENCE LTD, 2008)
Corresponding to the updated flow pattern map presented in Part I of this study, an updated general flow pattern based flow boiling heat transfer model was developed for CO2 using the Cheng-Ribatski-Wojtan-Thome [L. Cheng, ...
Evidences of turbulent mixing in multi-pumping flow systems
(ELSEVIER SCIENCE BV, 2009)
Multi-pumping flow systems exploit pulsed flows delivered by Solenoid pumps. Their improved performance rely on the enhanced radial mass transport inherent to the pulsed flow, which is a consequence of the establishment ...
Diffusional mass transfer coefficient at the water-sediment interface for wind-induced flow in very shallow lagoons
Very shallow lagoons that are a few centimeters deep are common in the arid Andes of Northern Chile, Argentina, Bolivia and Peru . The dynamics of these lagoons are dominated by the water-sediment interface (WSI) and strong ...
High performance simulations of electrokinetic flow and transport in microfluidic chips
(Elsevier Science Sa, 2009-12)
This article discusses high performance numerical simulations of electrokinetic flow and transport phenomena in microfluidic chips. Modeling grounds on conservation equations of mass, momentum and electric charge in the ...
