Instructor Biosketches

Professor Faith A. Morrison (current editor of the Rheology Bulletin) is Director of the Rheology Laboratory and Associate Professor in the Department of Chemical Engineering at Michigan Technological University in Houghton, Michigan USA. She is the author of Understanding Rheology, published by Oxford University Press in 2001. She has taught polymer rheology to undergraduates and graduate students at Michigan Tech since 1990 and recently established an undergraduate rheology laboratory there. This short course and the text Understanding Rheology represent a distillation of her 14 years of experience teaching rheology to beginners.

Professor A. Jeffrey Giacomin  is Chair of the Rheology Research Center and Professor of Mechanical Engineering at the University of Wisconsin at Madison. He teaches polymer processing and rheology to undergraduates every semester, and his research focuses on the role of rheology in plastics processing. Professor Giacomin is an expert on the measurement of the nonlinear viscoelastic properties of molten plastics, and on interpreting these measurements. His research group has published more than 50 refereed journal articles on rheology and plastics processing.

Professor Todd Squires is an Assistant Professor of Chemical Engineering at the University of California, Santa Barbara. His research group focuses primarily on microfluidics and microrheology – with particular emphasis on nonlinear electrokinetic flows, techniques for nonlinear microrheology, and interfacial microrheology. Among his publications is a substantial review of microfluidic physics.

Professor Patrick S. Doyle is Doherty Associate Professor in the Department of Chemical Engineering at the Massachusetts Institute of Technology. His research focuses on understanding the rheology and dynamics of single polymers, biomolecules (DNA, peptide gels), and magnetic colloids under forces and fields. His group has expertise in visualizing single DNA molecules in microfluidic devices using fluorescence microscopy and modeling complex fluids using Brownian dynamics simulations.

Professor Shelley L. Anna is Assistant Professor of Mechanical Engineering at Carnegie Mellon University. Her research interests focus on using microscale devices to synthesize structured materials such as precise emulsions and arrays of liquid crystalline defects. In addition to studying the formation of these structured materials, her group also develops methods of controlling and measuring their flow and interfacial behavior.

Professor Victor Breedveld is an Assistant Professor in Chemical & Biomolecular Engineering at the Georgia Institute of Technology since 2003. He received his MSc (1996) and PhD (2000) in Applied Physics from the University of Twente in the Netherlands and worked as a postdoctoral fellow at the University of California at Santa Barbara. Dr. Breedveld’s research focuses on the structure and rheology of complex fluids, with a particular interest in the development and use of novel experimental techniques to elucidate the microstructural dynamics of these materials. In 2006, he received an NSF-CAREER award.

Course Description

Beginning Rheology / Microfluidics for Rheologists

Beginning Rheology

Instructors: Prof. Faith A Morrison (FAM) and Prof. A. Jeffrey Giacomin (AJG)

The Beginning Rheology course is an introduction to the field of rheology meant for those with little or no background in rheology or rheological modeling. The course content is based on the text Understanding Rheology, by Faith Morrison (Oxford, 2001), which may be ordered at a discount at the time of registration for delivery at the short course. Although it is not possible to master rheology in a two-day short course, Beginning Rheology gives an overview of the subject, allowing attendees to delve further into the subject at a later time. Fundamental topics (introduction to the stress tensor, material functions, standard flows) are linked with more advanced topics (linear viscoelasticity, inelastic constitutive modeling) and industrial applications. In particular, the course is structured to help the student identify how different aspects of rheological modeling are related to a variety of industrial problems (fiber spinning, extrusion, structure-property studies, nonlinear modeling).

Part I: Basics
      A. Newtonian Fluids and the Analytical Tools of Rheology (FAM)
        Rheological Properties of Simple Fluids
          Stress Tensor
Newtonian constitutive equation
Predictions of stress, deformation in flows
    Characterizing Non-Simple Fluids
      Standard flows (shear, elongation)
Material functions (viscosity, elongational viscosity, start-up, step-strain)
  B: Low De, Low We Flows (AJG)
    A regime where Newtonian modeling is appropriate (fiber spinning, injection molding)
Part II: Inelastic Modeling
  A. Purely Viscous (Inelastic) Non-Newtonian Fluids (FAM)
    Generalized Newtonian constitutive equation
Power-Law model for viscosity (shear thinning/thickening)
Carreau-Yassuda model for viscosity
Bingham model for viscosity (yield stress)
Fitting viscosity models to rheological data
  B. Low De, Moderate to High We Flows (AJG)
    A regime where inelastic modeling is appropriate (inside extrusion dies)
Part III: Viscoelasticity
  A. Linear Viscoelastic Fluid Modeling (FAM)
    Memory effects – relaxation times, relaxation- time distribution
Maxwell model/Generalized Maxwell model (GMM)
Generalized Linear-Viscoelastic (GLVE) constitutive equation
Small-Amplitude Oscillatory Shear (SAOS) – G’, G”
Calculating relaxation time distributions from rheology
  B. High De, Low-Moderate We (AJG)
    A regime where linear-viscoelastic modeling is appropriate (Cox-Merz relation, structure property relations)
Part IV: Nonlinearities
  A. Non-Linear Viscoelastic Constitutive Modeling (FAM)
    Shear normal stresses, damping function in step strain, shear thinning
Strain tensors/convected derivatives
Nonlinear constitutive equations
  B. High De, High We (AJG)
    Non-linear viscoelastic modeling (film blowing, flow instabilities including slip and sharkskin)
Part V: Approaches to Complex Fluids
  A. Basic Polymer Molecular Modeling (AJG)
  B. Introduction to Complex Fluids (FAM)
    Suspensions, gels, and others

Microfluidics for Rheologists

Instructors: Prof. Todd Squires, Prof. Patrick S. Doyle, Prof. Shelley L. Anna, and Prof. Victor Breedveld

The last decade has witnessed an explosion of interest in microfluidics, buoyed in large part by the idea that microfabricated fluidic devices may revolutionize chemistry and biology, much as microchips did for computing, science and technology. Microfludic ‘labs on chips’ hold promise for automated and parallel experimentation, affording precise control over experimental conditions while requiring small volumes of materials that may be difficult or expensive to procure.

This promise holds for rheology as well both for scientific studies of rheologically interesting systems and for the creation and characterization of new materials. This one-day short course is designed to give the academic or industrial rheologist an overview of microfluidic systems, with the goal of giving participants the knowledge and intuition required to develop microfluidic capabilities in their own settings.

I. Introduction: capabilities and advantages inherent to microfluidics
II. How does one get started?
      a. Fabrication techniques and strategies (hard and soft)
b. Pumping, metering, mixing strategies
c. The newcomers’ “barriers to entry”: necessary expertise and equipment to start
III. An intuitive, ‘rule of thumb’ exploration of microfluidics
  a. Small-scale, viscous (Low-Re) flows
b. Diffusion, mixing and dispersion
c. Non-continuum effects
IV. Two-phase microfluidics: capillary effects
  a. Wetting phenomena
b. Designer droplets, emulsions and particles in microfluidics
c. Droplets as microreactors
V. Non-Newtonian microfluidics
  a. Single-molecule/droplet deformation studies
b. Non-Newtonian material flows
VI. Putting it all together: examples of and visions for microfluidic rheology
  a. On-chip measurements of intrinsic viscosity
b. Microfluidic microrheology of transient, solvent-responsive complex fluids
