**Course outline:**

This course will give students an overview of Non-Newtonian Fluid Dynamics, and discuss two approaches to building constitutive models for complex fluids: continuum modeling and kinetic-microstructural modeling. In addition, it will provide an introduction to multiphase complex fluids and to numerical models and algorithms for computing complex fluid flows.

**Prerequisites:**

Undergraduate-level course on Partial Differential Equations (MATH 257 or MATH 400), and graduate-level course on Fluid Mechanics (one of MATH 519, CHBE 557, MECH 502).

**Evaluation:**

The instructional format for the course will consist of lectures of 3 hours per week. The final grade is computed as such: 50% from cumulative marks of biweekly homework assignments, and 50% on a final presentation based on a cluster of research papers. There is no final exam.

To be assigned after class begins.
