Evaluation d’une méthode d’imagerie X en microfluidique : cas du remplissage de microcanaux en forme de « T »

Abstract : X-rays methods assessment in microfluidics: case of “T” shaped microchannels filling. Fluid flows within «T» or «Y» shaped microchannels are deeply studied in order to develop adapted modeling approaches and experimental techniques. Our technological choice lies on the attenuation measurement of X-ray in matter. The main advantage of this non-intrusive technique is to be implemented on medias opaque to visible light. Moreover, X-rays methods may achieve better spatial resolutions as compared to optical methods because of their much lower wavelength. In order to validate this X-ray method, measurements obtained by this technique are compared with direct measurements carried out on similar microchannels. Finally, experimental results are compared with a theoretical model.
