Why should you use CFD when we know empirical and semi-empirical models have worked before? correct answer: Because it is with CFD possible to model new equipment which has not yet been tested. Thus one can simulate performance of the equipment before spending tons of money to test in reality. What can you simulate with CFD? correct answer: CFD gives a detailed analysis of flows, heat transfer and mass transfer. Can study transport of chemical species, chemical reactors, combustion, evapora...
