Numerical And Experimental Investigation Of Fluidic Microdrops Manipulation By Fluidic Mono-Stable Oscillator

A numerical and experimental study of passive microdrops manipulation has been presented. This paper focuses on the modeling of micro-oscillators systems which are composed by passive amplifier without moving part. The characteristic size of the channels is generally about 3 5 mu m of depth. The numerical results indicate that the production and manipulation of microdrops are possible with passive device within a typical oscillators chamber of 2.5 mm diameter and 0:20 mm length when the Reynolds number is Re = 490. The novel microdrops method that is presented in this study provides a simple solution about the production of microdrops problems in micro system. We undertake an experimental step. The first part is based on realization of sample oscillator; the second part is consisted of visualization of the microdrops production and its manipulation.
