CFD is a tool that analyzes the flow, turbulence, pressure distribution, and interaction of liquids and gases with various structures. It is the science of predicting fluid flow, mass transfer, chemical reactions, and related phenomena. The CFD technology uses computers, computational methods, data of fluid viscosity, and fluid flow rates to simulate the flow of fluids. CFD is mostly used in the automotive, aerospace and defense, electrical and electronics, and energy industries for study related to thermal, acoustic, and air turbulence.
