Modelling of the coupling hydrodynamic transfer for a gas-liquid countercurrent flow on a wavy surface [PDF]

open access: yes, 2003
This paper concerns laminar countercurrent gas–liquid flow over a wavy wall column, in the case of a falling liquid film. The modelling concerns the coupling of hydrodynamic and heat and mass transfer for an absorption as an example of application.

Study on Antioxidant Activity of Catalyzed Hydrogen Degradation Product of Polymeric Proanthocyanidins (LPPC) from Larix gmelinii Bark

open access: yesBioResources, 2013
A grading countercurrent extraction method was used to separate polymeric proanthocyanidins (LPPC) from degreased Larix gmelinii bark, and the purification of LPPC was performed using HP-2MGL resin. The purity of LPPC was 26.37%.

Hydrodynamic and mass transfer efficiency of ceramic foam packing applied to distillation. [PDF]

open access: yes, 2009
In addition to a high void volume and specific area, solid foams possess other properties (low density, good thermal, mechanical, electrical, and acoustical behaviour) that make them attractive for applications such as heat exchangers and reformers ...
