Summary: The treatment of industrial effluents can be considered an essential factor for sustainable development. Among the advanced oxidative processes (AOPs) applied, heterogeneous photocatalysis stands out due to the possibility of using solar energy and because it occurs at ambient pressure and temperature. Its large-scale application depends on improving the performance of photocatalytic reactors, with the compound parabolic collector reactor being one of the most promising. In this context, the use of static mixers has emerged as an alternative to improve mixing parameters and increase the rate of pollutant degradation. Although there are studies evaluating the main commercial mixers or geometries developed by the author, there is a lack of analysis of the hydrodynamic effect of using mixers in heterogeneous photocatalysis processes. The aim of this work is to numerically evaluate the effect of changing the operating conditions of static mixers on the hydrodynamic behavior of the photocatalytic process in a compound parabolic collector reactor. To do this, the flow inside the reactor will be numerically simulated using Ansys CFX® software for Reynolds numbers of 4500 and 30000. The results will be compared with the literature to assess the effect of changing the geometry of the static mixer on the velocity profile, turbulence intensity and current line in the fluid flow in the reactor. It is hoped to contribute to the development of more efficient mixer applications by identifying relevant hydrodynamic aspects to obtain flows that promote intensified mixing and a better pollutant degradation rate.
