2. Rheology Research Laboratory
Rheology Research Laboratory

The rheology and non-Newtonian fluid mechanics (RNNFM) of suspensions and emulsions have been the central theme of The Rheology Research Laboratory. Our group has been doing researches on the migration and microstructure formation of particles suspended in Newtonian and non-Newtonian fluids under the non-homogeneous flow. We have been also working on the very dilute dispersion of nano-particles so called ‘nanofluid’. This smart fluid can be used for heat transfer enhancements. Currently we are deeply involved in the solution processing of suspensions for printed electronics. Specifically we have special interests on contact line motion, dispensing and inkjet printing of rheologically complex fluids. The generation of droplets of various complex fluids including nano-particle containing gels for rocket propellants is a newly added research subject.

3. Complex Fluids Engineering Laboratory
Complex Fluids Engineering Laboratory

Complex Fluids Engineering Laboratory (CFEL, Prof. Hyun Wook Jung) focuses on rheology and rheological processes based on theoretical modeling, simulation, and experiments. CFEL’s research fields are shown below.

  • Nonlinear dynamics/stability/sensitivity in polymer processes
  • Fundamental coating and drying processes
  • Micro-rheology using Brownian dynamics and light scattering techniques
  • Chemorheology and crosslinking characteristics of organic coatings
  • Suspension rheology
  • Macro-/micro-scale computations of exhaust gas flows inside porous filters

CFEL contributed to the product quality control and productivity enhancement in polymer extensional deformation processes such as film casting and film blowing, exhibiting Hopf bifurcation features. CFEL also established the key strategy for uniform coating flow control and operability windows in pre-metered coating processes which have been importantly applied in IT industries manufacturing display films, Li-ion secondary batteries, and fuel cells. CFEL elucidated the relationship between curing kinetics and mechanical properties of dual-curable organic coatings for automotive applications. Employing various light scattering techniques such as dynamic light scattering (DLS), diffusing wave spectroscopy (DWS), and multi-speckle DWS, CFEL have investigated the micro-rheological aspects in particulate suspension systems. Through Brownian dynamics simulations and related microfluidic experiments, CFEL clarified the migration and conformation of polyelectrolyte/biological polymer chains in various flow fields. CFEL recently performed macro/microscopic simulations for diesel particulate filters and developed coating technologies of catalytic slurries.
