Write a full mathematical description (PDEs, boundary
conditions, and if appropriate initial conditions) for 2 elliptic, 2 parabolic,
and 2 hyperbolic problems. One of these six must provide a mathematical
description of some simple fluid and/or heat transfer experiment.
Provide a full reference to the description of the experiment in a book
or journal, and photocopy of the page or pages giving a concise description
of the geometry of the apparatus. The paper that you use must contain
data that could be used to validate your mathematical model (and computational
solution).
