TL;DR: In this article, the main mass transfer resistance for CO2 capture in the gas-liquid membrane contacting process by both physical and chemical absorption conditions was characterized based on the resistance-in-series model as well as the Wilson-plot method.

TL;DR: In this paper, heat transfer coefficients were measured for circulating beds of sand particles of mean size 222 to 229m at temperatures of 340-880{degrees}C. Transfer coefficients were obtained for both a 1.22m-long, 12.7mm-OD vertical tube and a1.59-mlong, 148mm-wide membrane wall near the top of a 152mm-square by 7.32m-tall combustion column.
Abstract: Heat transfer coefficients were measured for circulating beds of sand particles of mean size 222 to 229 {mu}m at temperatures of 340-880{degrees}C. Transfer coefficients were obtained for both a 1.22-m-long, 12.7-mm-OD vertical tube and a 1.59-m-long, 148-mm-wide membrane wall near the top of a 152-mm-square by 7.32-m-tall combustion column. For both surfaces and all temperatures, average heat transfer coefficients increased almost linearly with local suspension density which ranged from 0 to 70 kg/m{sup 3}. Radiation played a significant role, especially at high temperatures and low suspension densities. Heat transfer coefficients also varied significantly with the lateral position of the tube. The vertical length of heat transfer surface is shown to be an important parameter allowing seemingly discrepant published results to be reconciled.

TL;DR: In this article, a volume-of-fluid (VOF) based simulation of coupled transport and reaction processes in micro-scale segmented flow microreactors is presented, which accurately captures the circulation patterns and micron-scale wetting film of the segmented flows.
