Abstract :
A fluidic flowmeter capable of measuring liquid flow rate in the micro-channel on the basis of the jet oscillation technology is presented. FLUENT is employed and numerical simulation is carried out to analyze the model of the micro-channel fluidic flowmeter, through which to study the characteristic and principle of the fluidic oscillation, optimize the structural parameters and establish the relationship between the flow velocity in the micro-channel and the frequency of the jet oscillation. The simulation results show that the oscillation of the fluidic flowmeter is stable, the jet switch is sensitive, and the Strouhal number is constant in certain range. To some extent, some effective methods for the design and optimization of the micro-channel fluidic flowmeter can be provided.
