A Working Definition of CFD
First, break down the words:
Computational - having to do with mathematics, computation
Fluid Dynamics - the dynamics of things that flow
This is CFD - a computational technology that enables you to study the
dynamics of things that flow. Using CFD, you build a computational model
that represents a system or device that you want to study. Then you apply
the fluid flow physics to this virtual prototype, and the software outputs
a prediction of the fluid dynamics. CFD is a sophisticated analysis
technique. It not only predicts fluid flow behavior, but also the transfer
of heat, mass (such as in perspiration or dissolution), phase change (such
as in freezing or boiling), chemical reaction (such as combustion),
mechanical movement (such as an impeller turning), and stress or
deformation of related solid structures (such as a mast bending in the
wind).
