Abstract :
This paper presents CFD-simulations of different diffuser elements used in valve-less diffuser pumps and nozzle elements used in dynamic micropumps. The results are compared with measurements and with analytic expressions based on empirical results known from basic fluid mechanics. The working principles of the diffuser element in the valve-less diffuser pump and the nozzle-element in the dynamic micropump are investigated
