This poster studies catalytic micropumps and their ability to induce fluid flow on the microscale. The goal of the study is to design a long-distance, directed convective loop. An array of catalytic micropumps was constructed in the domain, comprised of two distinct catalysts in an alternating pattern with a uniform concentration of their respective reagents in the surrounding geometry. Two reactions take place, and convective loops appear with a dependence on the study's parameters. These parameters include the distance between each pump, the ratio of the two reaction rates, and the direction of fluid flow near each micropump. The results feature graphs of the pumping velocity over 1-D cutplots from the domain and a time-lapse of the optimal conditions.
