摘要：

The microscopic liquid flow characteristics of the structured corrugation foam packing (SCFP) sheets with different combinations of the pore size and the extrusion ratio are observed experimentally in this paper. The tracks of liquid water under different flow rates were recorded by a high-speed camera with a micro lens. A combination of liquid film and quasi-wall flow is verified as the unique liquid flow pattern in SCFP sheets. Besides, the study on the liquid transportation of combined SCFP sheets is carried out. Furthermore, the liquid flow characteristics of SCFP sheets are compared with two classical packing sheets widely used in distillation. The comparison results demonstrate that the unique three-dimensional network structure of SiC skeleton makes SCFP sheets realize larger liquid dispersion degree for single corrugated sheet and better liquid transportation capability for combined corrugated sheets. The study suggests that SiC-foam material has a broad application prospect in the field of structured packing. © All Right Reserved.
