ABSTRACT
Owing to rapid development in computer hardware in recent
years, numerical simulation has been highlighted as an approach
to solve problems in science and engineering. The numerical
calculation is widely accepted in the ield of engineering, because
it has several advantages in swiftness, safeness and cost compared
with experimental trial. As it has the potential to simulate complex
phenomena that are dificult to measure and analyze mathematically,
it is also the principal method in fundamental research. The solution
of phenomena in low by numerical calculation and the academic
ield of numerical calculation method itself are called numerical
luid dynamics and also computational luid dynamics. The
numerical calculation has a wide ield application such as low in
space, weather and ocean, and also airplanes, ships, trains and cars.
