Abstract :
A feedback-driven microfluidic oscillating flowmeter for the need of the miniaturization of flow sensors in the MEMS flow control system is presented. Numerical simulation method is employed to study the measurement characteristics of the microscale fluidic flowmeter, the simulation results show that this microfluidic oscillating flowmeter has the feature of oscillation stable, sensitive switch, the Strouhal number being a const in a wide range of the inlet velocity and the small initial oscillation velocity down to 0.075m/s. The attempt in this work may provide some useful information for design and optimization of the microscale fluidic flowmeter.
