High Quality Content by WIKIPEDIA articles! CFD stands for computational fluid dynamics (and heat transfer). As per this technique, the governing differential equations of a flow system or thermal system are known in the form of Navier–Stokes equations, thermal energy equation and species equation with an appropriate equation of state . CFD technique can be applied in those problems where, some kind of fluid flows, heat energy transfer takes places. This technique is very well known since 1960`s but at that time its use was confined to only aerospace industry.
