What is fluid flow?
Fluid flows encountered in everyday life include
• meteorological phenomena (rain, wind, hurricanes, floods, fires)
• environmental hazards (air pollution, transport of contaminants)
• heating, ventilation and air conditioning of buildings, cars etc.
• combustion in automobile engines and other propulsion systems
• interaction of various objects with the surrounding air/water
• complex flows in furnaces, heat exchangers, chemical reactors etc.
• processes in human body (blood flow, breathing, drinking . . . )
• and so on and so forth
What is CFD?
Computational Fluid Dynamics (CFD) provides a qualitative (and
sometimes even quantitative) prediction of fluid flows by means of
• mathematical modeling (partial differential equations)
• numerical methods (discretization and solution techniques)
• software tools (solvers, pre- and postprocessing utilities)
CFD enables scientists and engineers to perform ‘numerical experiments’
(i.e. computer simulations) in a ‘virtual flow laboratory’
