Analysing transfer phenomena in osmotic evaporation
(Univ Nac Colombia, Fac IngenieriaBogotaColombia, 2011)
Effect of the number of orifices and operative variables on the heat and mass transfer in a hydrofluidization system with static spheres
Hydrofluidization is a method of chilling and/or freezing that uses submerged jets of a refrigerating liquid. The objective of this work was to study the effect of refrigerant temperature (-5°C, -10°C), fluid velocity at ...
An analysis of the effects of nanoparticles deposition on characteristics of the heating surface and ON pool boiling of water
Nanofluid pool boiling can modify the morphology of the heating surface and the physical properties of the base fluids, interfering directly on the vapor bubbles dynamics and on the heat transfer mechanisms. This paper ...
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 ...
Oxygen mass transfer studies on batch cultivation of P. aeruginosa in a biocalorimeter
(Pontificia Universidad Católica de Valparaíso, 2008)
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 ...
Thermal analysis of a rotary regenerator with fixed pressure drop or fixed pumping power
(Pergamon-elsevier Science LtdOxfordInglaterra, 2013)
Experimental analysis of heat transfer in packed beds with air flow
Heat-transfer studies were carried out in a packed bed of glass beads, cooled by the wall, through which air percolated. Tube-to-particle diameter ratios (D/dp) ranged from 1.8 to 55, while the air mass flux ranged from ...
