摘要

In order to expand the back pressure and increase the net flow rate of the micropump, so as to achieve the purpose of being applicable to high-performance industrial and medical microsystems, a complete set of theoretical and numerical modeling methods are proposed in this paper to design for enhancing system efficiency of a bio-inspired chamber for the valveless micropump. To ensure the design goal can be achieved, a two-way fluid-solid coupling interface system (FSIS) is adopted for design analysis of the bio-inspired chamber structure. The design and numerical simulation process indicates that when the peak voltage is of 100 V and working frequency is at 40 Hz, maximum net flow rate of the bio-inspired micropump is 1.89 ml/min and maximum back pressure is 720 PA (or 5.4 mmHg), which are better than that of the conventional micropump with circular geometry. Also, the net flow rate of the bio-inspired system is 44% higher than that of the conventional micropump. The results also reveal that the internal flow state of the bio-inspired valveless micropump possesses a significant impact on the increase of the natural frequency of the system. Since the system resonance frequency thus induced is much higher, the net flow rate of the bio-inspired micropump is thus effectively increased. By comparing with the measured data of the conventional circular valveless micropump system, it is proved that the bio-inspired chamber design proposed in this paper is highly feasible.
