ABSTRACT:
Two or more liquids are mixed continuously in very short times and in a highly uniform manner. Thin sheets of the liquids to be mixed are formed and contacted to produce a new mixed sheet. The newly formed mixed sheet is highly turbulent which substantially enhances mixing. Since the contacting of the liquids occurs on a scale of microns of thickness, mixing is not only rapid but complete and extremely uniform as well. Turbulence within the mixed sheet that further enhances mixing allows for mixing times as low as 0.1 millisecond, depending on flowrate and pressure drop, for low viscosity fluids.
