The performance of heat exchangers can be assessed with
CFD. This is particularly important for situations where the
exchanger configurations are different enough so that
empirically based correlations are inapplicable. However,
the calculation of heat transfer coefficients is not a trivial
problem in CFD. Also not all situations can be modeled
effectively.
Flow distributions around heat exchangers can be modeled
including natural convection effects which are significant in
still fluid conditions.
