Abstract

Hydrodynamic studies results are presented for O/W and W/O emulsions, biological dispersion as a human blood in microchannels obtained both by traditional methods and soft lithography ones. It’s shown that a general property of dispersions flow in microchannels is the dynamic blocking phenomenon. An analysis of blood and emulsion rheological properties is provided by data got with a precision rheometer. Experiments using microfluidic devices supported to detect droplet deformation during the dynamic blocking and an asymmetry of the dispersion flow pattern ina stepped constriction.
