尾鳍对无阀压电泵性能的影响分析与试验研究
Analysis and test on influence of caudal-fin on performance of valveless piezoelectric pump
摘要
Abstract
In order to study the performance of a valveless piezoelectric pump with caudal -fin and identify the influence of piezoelectric vibrator caudal-fin on the pumping flow,a modal analysis on wetted piezoelectric vibrator caudal-fin was conducted in ANSYS.The first three working frequencies and corresponding vibration modes were obtained.Then the flow and performance of the piezoelectric pumps with and without caudal-fin were simulated by making use of Fluent,and compared with the experimental results.In simulations,when the excitation peak voltage is 100 V and the frequency is 800 Hz,the pumping flow in the piezoelectric pump with caudal-fin is 65 .34 mL/min,while it is 5.32 mL /min in the pump without the fin.In experiments,when the excitation peak voltage is 100 V and the frequency is 800 and 760 Hz,the pumping flow in the piezoelectric pump with caudal-fin is 60.25 and 75.65 mL/min,but it is 4.10 and 4.60 mL/min in the pump without the fin,respectively. This is proved that the extra flow rate in the valveless piezoelectric pump with caudal-fin is mainly caused from the caudal-fin driving effect.Based on the comparison of tested and experimental pum-ping flow rate,the correctness of simulation analysis has been confirmed.关键词
