| Abstract: | The pressure distributions of the diffuser and the nozzle of valve - less micro - pump were analyzed theoretically, the basic flow equations were obtained. The finite element method was applied to calculate the velocity and pressure fields of the diffuser and the nozzle numerically, and the factors which influences the flow characteristic of the valve - less micro - pump were investigated. The research results have significant to the design of the diffuser and nozzle of the valve - less micro - pump. |
