OVERVIEW: The motion
of fluids holds both aesthetic and practical fascination for humans. The
science of fluid mechanics provides insight into phenomena as diverse as
wave action, ocean circulation, weather patterns, the destructive power
of tornados and hurricanes, the science of flight, shock waves, the droplet
pattern in a half-empty wine glass, the laminar-turbulent transition of
a smoke plume rising from a cigarette, blood flow in the heart, and the
accretion of galaxies. Because of the complicated nature of the Navier-Stokes
equations that govern fluid motions, prior to the second half of the 20th
Century, fluid dynamicists could rely only upon simplified theories corroborated
by physical experiments to explain and predict fluid-flow phenomena. With
the advent of the digital computer, numerical simulation joined theory
and experiment in the arsenal of scientific techniques that can be brought
to bear in unraveling the mysteries of fluid flow. To date, the quest for
a virtual wind tunnel to replace the physical wind tunnel has been somewhat
illusory. Nevertheless, with continuing advancements in both computer technology
and algorithmic efficiency, computational fluid dynamics has emerged as
a powerful and (in the right hands) trustworthy tool for the design of
spacecraft, aircraft, and automobiles. In the future, numerical simulation
will become ever more important as an emerging "key technology." Say the
authors of our text: "The numerical simulation of physical phenomena requires
the observations and models of the natural scientist, the technical expertise
of the engineer, the numerical methods of the mathematician, and the modern
techniques and computers of the computer scientist." This course has been
specifically designed as an integral part of JMU?s and NCCU?s collaborative
NSF-funded computational-science
track to help you--the student--develop and hone the triad of skills
that comprise a solid foundation in computational science: modeling
of physical phenomena, numerical methods, and scientific visualization.
