An Advanced Liquid Centrifuge Using Differentially Rotating Cylinders and Optimized Boundary Conditions --- Inventor(s) Hantao Ji, Adam Cohen, Phil Efthimion and Eric Edlund

This invention discloses a concept for an advanced centrifugal contactor which can be used for (1) mixing of two or more component fluid substances to produce a uniform mixture or enhance the rate of a chemical reaction and (2) for the segregation of mixtures of fluids or suspensions into separate parts based on differences in density. The mechanical system that allows for this dual-purpose function is the presence of an inner-cylinder (IC) and an outer-cylinder (OC) which rotate independently of each other so as to generate a sheared flow in the fluid.  One application is to control stages of mixing, for example by first injecting and mixing two fluids to promote a chemical reaction under turbulent flow, and then changing speeds to separate the reaction products.
