The plug flow reactor (PFER) using porous reticulated electrode (PRE) provides a novel mass transfer mode for electrochemical reaction, in which the fluid flow is perpendicular to the surface of PRE. By this promising reactor, the turbulence intensity and mass transfer can be strongly improved and thus the key problem in engineering scale-up may overcome. We plan to investigate the effects of flow character at PFER and the degradation of pollutant, as well as coupled fluid diffusion mechanics and chemical reaction process by combining particle image velocimetry and fluid dynamic calculation. The PFER using PRE is carried out by multi-scale numerical simulation on the degradation of organic pollutants for wastewater treatment. The objective of the project is to elucidate the information on degradation of pollutants in the new reactor, and to reveal the influence including the reactor structure, the fluid boundary layer turbulence, the flow turbulence intensity, and mass transfer of pollutants at the PRE surface. In conclusion, the project has important scientific significance, not only on providing new approaches for preparation of novel electrochemical reactor but also on promoting disciplinary crossing and integration, such as fluid machinery and engineering, electrochemistry, environmental engineering, and so on.
