Abstract: The fluidic oscillator is a new micro-scale actuator developed for flow control applications. Mixing in micro channels is an important problem because the flow is always laminar flow even though the velocity may be high. The principal constraints when designing a mixer are the flow rate required through that particular section of the micro-device, the fluid properties of the streams to be mixed and the desired level of mixing. This paper describes a new actuator for flow mixing applications with nozzle size equal 1.18 mm. The gas diffusion, mixing is very important operation in the fields of nature and industry. Now, it is desired to improve the mixing. In this paper, first the performance of fluidic oscillator mixer operated by gas is made clear simulation.


Keywords: Mixture, Diffusion, Oscillator, Mixer auto pulsed
