A 3D passive micromixer for synthesizing nanoparticle with bio-applications: Computational study

One of the main applications of micromixers is nanoparticle synthesis. Nanoparticles can be utilized in many bio-applications for instance, they can use in many bio-applications, for example, they can used as drug carriers to deliver and release drugs to targeted cells and tissues. A faster mixing process creates small and uniform nanoparticles, while a slower mixing process results in larger nanoparticles with varying sizes. In this paper, a 3D passive micromixer with novel geometry is presented. A numerical study has been done, Navier-Stokes, species transport, and continuity equations are solved with the finite element method to analyze the mixing index, effective Reynolds numbers, and the pressure fall. for Reynolds numbers 10 to 420. Mixing time was also calculated with the Falk and Commenge equation, and Results were compared with previous experimental data to see whether the micromixer’s performance in producing nanoparticles was satisfactory or not. All in all, the proposed micromixer demonstrate a significant performance in a wide range of Reynolds number and can be suitable for high-throughput nanoparticle production.
