Geometrical analysis of diffuser-nozzle elements for valveless micropumps

This paper reports a geometrical analysis and tuning-approach for diffuser-nozzle elements for valveless micropumps. Finite element analysis studies are performed in order to investigate the impact of the angle, curvature ratio, and length of the diffuser on the pumping efficiency. Parametric sweep...
