Application of computational fluid dynamics in chemical engineering

Computational fluid dynamics(CFD) involves the numerical solution of conservation equations for momentum,energy and mass in a flow geometry of interest,together with additional sets of equations reflecting the problem at hand.It is a very powerful and important tool of studying flow field and mass transfer in the chemical engineering.In this paper the general principle of CFD and the application of CFD in chemical engineering are reviewed and especially the application of CFD in stirred tank,heat exchanger,distillation tray,thin-film evaporator and combustor is introduced.
