We analyzed microfluidic oscillators operating with liquids (water, isopropilic alcohol, and acetone) or gases (nitrogen, argon, and carbon dioxide), using numerical simulation. The possible applications include rapid measurement and control of low fluid flows in areas as automatic control in industries, measurement in domestic gas storing, chemical or biological analysis, etc. In this case, the devices should possess easy maintenance and manipulation characteristics. And, the devices described in this work present potential to address satisfactorily all these requirements. For simulations, using the ANSYS 5.7 commercial package, the dimensions were derived from those of a typical wall attachment microfluidic amplifier. The results of these calculations indicate that conventional steady state and dynamic transient analysis are useful tools for evaluating fluidic oscillator in the micro dimension scale.
