Microreactors are flow systems with small channels designed to control fluid flow. A key component of these systems is the micromixer, which efficiently mixes fluids at the micron level. This master's thesis presents the optimization of the geometry of a passive slanted groove micromixer. We designed new groove shapes and evaluated their mixing efficiency using CFD simulations, which we validated against experimental results from the literature. The best design was found to be the groove geometry with roundings on both sides. Using additive technologies and soft casting of the PDMS polymer, we fabricated a prototype of the best design. Experimental validation showed that the flow pattern matched the simulated flow profile.
