摘要：A valveless piezoelectric pump with rotatable unsymmetrical slopes is developed in this research.It has the following features:The pump integrates driving and transporting,and it can mix different fluids while transporting them.In this paper,firstly,the design of the valveless piezoelectric pump with rotatable unsymmetrical slopes was proposed,and the single-direction flow principle was explained.Then,the fluid mechanics model of the valveless piezoelectric pump with rotatable unsymmetrical slopes was established.Meanwhile,the numerical simulation of the pump was performed.Finally,the experiments on relationship between the rotation angles of the slope and the flow rates were conducted.The experimental results showed that the maximum flow was 32.32 mL min 1.The maximum relative error between the theoretical results and the experimental ones was 14.59%.For the relationship between rotation angles and flow ratio of two inlets,the relative error between the experimental and theoretical maxima was 3.75%.Thus,the experiments proved the feasibility of the pump design and verified the theory.

Then, the fluid mechanics model of the valveless piezoelectric pump with rotatable unsymmetrical slopes was established. Meanwhile, the numerical simulation of the pump was performed. Finally, the experiments on relationship between the rotation angles of the slope and the flow rates were conducted. The experimental results showed that the maximum flow was 32.32 mL min(-1). The maximum relative error between the theoretical results and the experimental ones was 14.59%. For the relationship between rotation angles and flow ratio of two inlets, the relative error between the experimental and theoretical maxima was 3.75%. Thus, the experiments proved the feasibility of the pump design and verified the theory.
