CFD and FLUENT
What is CFD? CFD is the abbreviation for “Computational Fluid Dynamics” and a branch of fluid mechanics to predict the behavior of a fluid flow with the help of numerical methods and (fast) computers. the most common understanding of CFD is solving non-linear partial differential equations which describe the fluid flow behavior with the aid of numerical methods rather than analytical or experimental ones. While, there are methods in the scope of CFD, which are independent from those usual partial differential equations (SPH). Hence, CFD is a quite powerful tool for engineers to predict the behavior of the systems including fluid flows, where the exact analytical answers are not available (and this is a common practice most of the time!)
What is FLUENT? FLUENT is a commercial CFD package and can be used in most industries. It is fairly simple and user-friendly, but at the same time enough powerful for many engineering purposes. In fact FLUENT is one of the best in its kind.
