| Abstract: |
| Biofuels are known as sustainable alternatives for fossil fuels and new technologies for intensification of their production are being developed. Oscillatory baffled reactors (OBRs) are a novel approach to process intensification of biofuel production. The diverse geometry of baffles inside this type of reactor has a substantial impact on the mass and heat transfer and it determines the application of the OBRs. Baffles serve the purpose of facilitating improved mixing within the reactor by directing the fluid flow. In this study, the effects of different baffle geometries on the mixing performance parameters, namely pressure drop, energy dissipation, and the characteristics of flow and shear strain rate fields were reviewed. The five geometries examined include the single orifice baffle, the disc-and-donut baffle, as well as three new variations of helical blades (as the most well-known shapes). Moreover, the baffle spacing factor and its influence on the dispersion and residence time were analyzed. The results of the previous research showed that the type of baffle design influences the fluid behavior in the reactor. However, this study shows that each geometry and size can be beneficial for a specific application of processes within the reactor and one model cannot be used as the most optimal model for all processes, and choosing the best type of baffle to optimize the mixing and construction of oscillatory reactors on scales larger than laboratory scales can be challenging. |
