2005. Учебный курс по вычислительной газовой динамике. Лекции, разбор задач (на англ. яз.)Computational fluid dynamics (CFD) is the use of computers and numerical techniques to
solve problems involving fluid flow.
CFD has been successfully applied in a huge number of areas, including many of interest to
civil engineers (highlighted below). Examples include:
aerodynamics of aircraft and automobiles;
hydrodynamics of ships;
engine flows – IC engines and jet engines;
turbomachinery – pumps and turbines;
heat transfer – heating and cooling systems;
combustion;
process engineering – mixing and reacting chemicals;
windpower;
wind loading – forces and dynamic response of structures;
building ventilation;
fire and explosion hazards;
environmental engineering – transport of pollutants and effluent;
coastal and offshore engineering – loading on coastal and marine structures;
hydraulics – pipe networks, reservoirs, channels, weirs, spillways;
sediment transport – sediment load, scour and bed morphology;
hydrology – flow in rivers and aquifers;
oceanography – tidal flows, ocean currents;
meteorology – numerical weather forecasting;
high-energy physics – plasma flows;
biomedical engineering – blood flow in heart, veins and arteries;
electronics – cooling of circuitry.
The range of applications is broad and encompasses many different fluid phenomena. In
particular, techniques used for high-speed aerodynamics (where compressibility is significant
but viscous effects are often unimportant) are different from those used to solve low-speed,
frictional flows typical of hydraulic and environmental engineering. Although many of the
techniques learnt in this course will be general, the focus will be on simulation of viscous,
incompressible flow by the finite-volume technique.CFD process
