Complex Fluid Systems

The complex fluid systems program investigates non-Newtonian, multiphase, turbulent, and/or chemically reacting flows over multiple length and time scales. We develop unique experimental and computational techniques that advance our understanding of fluid flow phenomena and enable engineering applications, including fuel and chemical production; biomass transport; particle dispersion; and heat exchangers in evaporators, boilers, and condensers. The efforts of this program pioneer new theories and models of complex fluid processes and validate these processes through novel experimental techniques and exploration tools.
