TWO-PHASE FORCED CONVECTION HEAT-TRANSFER DURING CONDENSATION ON HORIZONTAL TUBE BUNDLES
Résumé
Existing published methods for the calculation
of heat-transfer coefficients in design for
condensation on tube bundles do not represent the
interactive effects of interfacial shear and condensate
inundation. With significant shear the
heat-transfer process is two-phase forced convection
and an appropriate correlation is derived in
this paper using published data from small-scale
experiments on both triangular and square pattern
tube bundles. The predictions of methods based on
(a) the two-phase correlative approach and (b) a
published theoretical model for vapour shear on a
single tube together with an inundation term are
compared with the data and the relative performance
of the methods is discussed.
