One promising geometry is based on an opposed-jet configuration, having an X-shape with two inlets and two outlets. However, little is known about the resulting mixing and reaction performances. This work aims at gaining insight into the flow regimes occurring in this microdevice and into how they impact the progress of a chemical reaction. To this purpose, we carry out experimental flow visualizations and numerical simulations at different Reynolds and Damköhler numbers and we provide quantitative trends of the mixing degree and reaction yield for the different flow regimes.
