Complex Fluids and Multiphase Flows

Complex fluids are fluidic mixtures featuring multiple phases and mesoscopic length scales, and include atmospheric aerosols, polymeric solutions and colloidal suspensions. An exciting feature of many complex fluids is their unusual response to external stimulus, such as thermal, chemical, mechanical, electrical or inertial forcing. The intricate dynamics observed in complex fluids, if well understood, can be engineered for numerous applications.

Our group's research interests are in fundamental studies of the dynamics, bifurcations and patterning of complex fluids and multiphase flows, with a specific focus on environmental remediation. Using laboratory experimental techniques and analytic mathematical modeling, we explore such areas as the thermodynamics of electrolyte-containing atmospheric aerosols, fluid dynamics and rheology of polymeric solutions, and microfludics of multiphase flows.


February 2018: Athena Metaxas's paper "Extensional flow behavior of methylcellulose solutions containing fibrils" was accepted by ACS Macro Letters. This was a MRSEC supported co-first authored work by Svetlana Morozova, Peter Schmidt and Athena from the Lodge, Bates and Dutcher groups. Congrats Athena, Peter, and Sveta!

January 2018: Eric Ruud's paper "Electrohydrodynamic aggregation with vertically inverted systems" was accepted by Physical Review E. Congrats Eric!

January 2018: Lucy Nandy's paper "Phase Behavior of Ammonium Sulfate with Organic Acid Solutions in Aqueous Aerosol Mimics Using Microfluidic Traps" was accepted by Journal of Physical Chemistry B. Congrats Lucy! JPC B microfluidic wells.

January 2018: Audrey Sebastian joined the lab as an undergraduate researcher. Welcome Audrey!

December 2017: Nikolas Wilkinson has passed his PhD defense. Congrats Dr. Wilkinson!

November 2017: Andrew Metcalf and Shweta Narayan's paper "A Review of Microfluidic Concepts and Applications for Atmospheric Aerosol Science" was accepted by Aerosol Science and Technology. Congrats Andrew and Shweta! AS&T.

October 2017: Thomas Neumiller joined the lab as a 1st year ME PhD students. Welcome Tom!

October 2017: Professor Dutcher was awarded American Association for Aerosol Research (AAAR) Kenneth T. Whitby award. The Whitby award recongnizes outstanding technical contributions to aerosol science and technology by a young scientist. The aerosol thermodynamics and microphysics work being recognized is the result of outstanding research efforts by former and current Dutcher lab members Andrew Metcalf, Hallie Boyer, Lucy Nandy, Shweta Narayan and Peter Ohm. Congrats to all!

October 2017: Nikolas Wilkinson and Athena Metaxas's paper "pH Dependence of Bentonite Aggregate Size and Morphology on Polymer-Clay Flocculation" has just been accepted for publication in the Colloids and Surfaces A: Physicochemical and Engineering Aspects! This was the third paper in a fruitful MRSEC supported collaboration with Prof. Theresa Reineke's group in the Department of Chemistry. Congrats to All! Colloids and Surfaces A.

September 2017: Shihao Liu joined the lab as a 1st year ME PhD student. Welcome Shihao!
