The study of incompressible ?ows is vital to many areas of science
and te- nology. This includes most of the ?uid dynamics that one
?nds in everyday life from the ?ow of air in a room to most weather
phenomena. Inundertakingthesimulationofincompressible?uid?ows,
oneoftentakes many issues for granted. As these ?ows become more
realistic, the problems encountered become more vexing from a
computational point-of-view. These range from the benign to the
profound. At once, one must contend with the basic character of
incompressible ?ows where sound waves have been analytically
removed from the ?ow. As a consequence vortical ?ows have been
analytically "preconditioned," but the ?ow has a certain
non-physical character (sound waves of in?nite velocity). At low
speeds the ?ow will be deterministic and ordered, i.e., laminar.
Laminar ?ows are governed by a balance between the inertial and
viscous forces in the ?ow that provides the stability. Flows are
often characterized by a dimensionless number known as the Reynolds
number, which is the ratio of inertial to viscous forces in a ?ow.
Laminar ?ows correspond to smaller Reynolds numbers. Even though
laminar ?ows are organized in an orderly manner, the ?ows may
exhibit instabilities and bifurcation phenomena which may
eventually lead to transition and turbulence. Numerical modelling

insight into the relationship of the numerical methods with the ?ow
