Science, which deals with the calculation of different flow parameters in a fluid continuum, with the help of a computer
Equations that are known are programmed into computers The computers provide solutions to the problem of external airflow over vehicle shapes The body of the configuration and the space surrounding it are represented by clusters of points, lines and surfaces; equations are solved at these points CFD is divided into three steps Grid generation, numerical simulation and post-process analysis Here are some examples of CFD data sets
a computer-based numerical study of turbulent fluid flow using approximate methods such as the finite element method, the fine difference method, the boundary element method, the finite volume methods, and so on
the science of determining a numerical solution to the governing equations of fluid flow whilst advancing the solution through space or time to obtain a numerical description of the complete flow field of interest
Computational fluid dynamics is the term given to a variety of numerical mathematical techniques applied to solving the equations that govern fluid flows and aerodynamics
