This course will
offer an introduction to fluid dynamics and its applications in
biology. In particular we will spend time discussing blood flow in
arterial networks. The course will study fluid mechanics from a
mathematical perspective, including examples from biological
applications. Students will work on an independent project that
can be taken from their research. The course is suitable for
advanced undergraduate and graduate students in mathematics,
bio-engineering, and mathematical biology. Topics will include
physical concepts such as viscosity, vorticity, shock waves, flow
in tubes and pipes, stokes flow, boundary layers, and potential
flow. Biological applications will include swimming, flying, and
blood flow in networks of arteries.

During the course a number of smaller and larger homework
projects will be assigned. Students should be prepared to
discuss results of homework problems on the board or using
electronic media in class. While homework problems can be worked
out in a group, everybody should be able to discuss the solution
to a given homework. In addition to homework problems, one
in-class (mid-term) and one take-home (final) test will be
given. Results of the take-home test should be typed up and
handed in electronically.
Evaluation criteria:The course will be
graded based on the work performed in homework (40% of grade),
group project (20% of grade), and tests (midterm 20% and final
Basic understanding of mechanics, vector calculus, matrices,
ordinary differential equations. Other mathematics and physics
will be reviewed as needed.
Homework: I encourage you to work with others on the
homework, but remember - if you work with someone else, put
all names on the paper for a common grade. If computers are
used for solving aspects of an homework problem (e.g., Maple,
Matlab, XPP, or Mathematica) you must indicate so on the
homework. Nicely commented computer code should be attached as
part of the homework. Points will be deducted for homework
handed in late - graded homework can be reworked for some
extra credit. Some homework problems will be discussed in
class, and I will call on you to go through your solution on
the board. For homework, anyone in the group can be called to
discuss the solution of any problem.
