What is CFD?

Computational fluid dynamics (CFD) is a branch of fluid mechanics that utilizes numerical analysis to digitally predict fluid flow. Fluid mechanics plays a significant role in the engineering and design process. Analyzing aerodynamic and thermal performance of a product using an experimental process can be costly, limiting, time-consuming and difficult to execute on a large scale. Computing power has allowed the field of CFD to act as a complement to physical testing and in some cases, replacing it. CFD allows engineers to predict fluid flow, heat transfer, mass transfer, chemical reactions and other flow properties by solving governing fluid flow equations. It is widely used across all industries.
