| Abstract: | A lumped-mass model is used to improve the design of the valveless diffuser pump. The model is implemented using MATLAB and tested for different previously reported pumps. The flow-pressure characteristics are predicted for different excitation levels. It is seen that low chamber pressure limits the possible excitation level. A pump with two serially connected pump chambers working in anti-phase is found advantageous compared with a single chamber pump. Indication is found that down scaling of the diffuser elements from 80ïïïï80 µm throat cross-sectional area to 40ïïïï40 µm throat cross-sectional area increase the attainable pressure head. The possibility to use deposited PZT instead of discs fixed with adhesive is shown promising. |
