2022, International Journal of Heat and Mass TransferCitation Excerpt :Micro/nano-scale features can lead to a significant change in surface wettability, which contributes to an increase in the surface hydrophobicity and a reduction in the frictional resistance. As for condensation on coating surfaces, flow parameters of fluid [11,12], geometry parameters of surface [3,13-15], chemical components of surface [16,17], noncondensable gas effects [18], and wetting characteristics of surface [4,19] have significant influences on CHTC during convective flow condensation. Ding et al. [20] investigated R141b convective condensation heat transfer characteristics inside a rectangular microchannel with a hydraulic diameter of 0.67 mm and a mass flux range of 70 kg/(m2 s) to 850 kg/(m2 s).

2015, International Journal of Heat and Mass TransferCitation Excerpt :To enhance the convection–condensation heat transfer between bundles and a fluid, some approaches by modifying the heat transfer surface are used, such as porous medium coated surface. Renken and Raich [14] have presented experimental results for force convection pure steam condensation heat transfer on an impermeable porous-layer coated surface. Results show the porous coating produces a considerable heat transfer enhancement (250% higher) compared with noncoated surface.
Experimental study of flexible, unstructured metal foams as condensation structures
2014, Experimental Thermal and Fluid ScienceCitation Excerpt :Some initiatives regarding the use of porous media for condensing water in saturated vapor environment can be found in the literature. Renken and Raich [12], experimentally studied the forced convection heat transfer of an isothermally cooled, flat impermeable condensing surfaces, which was assisted by a relatively thin, highly conductive and permeable porous coating. The plate was placed parallel to saturated steam (vapor) flow and this combination was tested in different angles, from vertical to horizontal positions.
Numerical modeling and simulation of condensation heat transfer of a flue gas in a bundle of transport membrane tubes
2013, International Journal of Heat and Mass TransferCitation Excerpt :There are a few studies on porous wall tube bundles using air, which actually do not involve condensation process [18,19]. Renken and Raich [20] investigated force convection pure steam condensation enhancement using porous-layer coated surface, but the surface is impermeable. To the best of our knowledge, heat transfer of multi-species flue gas with mass transfer on the porous wall of a tube bundle has not been investigated.
