CFD - computational fluid dynamics

A Working Definition of CFD by Fluent

Computational - having to do with mathematics, computation; Fluid Dynamics - the dynamics of things that flow.

CFD is 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).

Qualitatively, we consider the CFD predictions to agree well with the data if the model and experimental results are within a factor of two (Finlayson et al., 2004 E.U. Finlayson, A.J. Gadgil, T.L. Thatcher and R.G. Sextro, Pollutant dispersion in a large indoor space: Computational Fluid Dynamics (CFD) predictions and comparisons with a scale model experiment for isothermal flow, Indoor Air 14 (2004) (4), pp. 272¨C283.)
