Abstract :
A fluidic flowmeter with new structure is designed in this work on the basis of the traditional ones in order to obtain wide measurement range. This fluidic flowmeter has the diffuser wall with polygonal line and it has the performance of adaptability and stability. The CFD software FLUENT is employed to the numerical simulations of the fluidic flowmeter. The linear-relationship of oscillation frequency flowrate is obtained in the wide measurement range through the analysis of the data. The simulation results show that the oscillation of this fluidic flowmeter is stable and reliable. The formula of the flowrate and the oscillation frequency is obtained. The lower limit of the measurement and the pressure loss of the oscillator are also analyzed. Some useful theoretical information can be provided for the design of fluidic flowmeter in this work.
