LOCAL HEAT AND MASS TRANSFER CORRELATION IN HORIZONTAL STRATIFIED COCURRENT FLOW
Résumé
The local heat and mass transfer coefficients
of horizontal stratified cocurrent
flow have been successfully correlated for an
extensive data set including the Northwestern
data as well as others. The generalized transport
coefficient (heat transfer for condensing
flow and mass transfer for gas absorbing flow)
is proportional to u*, the interfacial shear
velocity, and Prandtl or Schmidt number. A
mechanistic model of turbulence transport in
the liquid phase based on a modified Lamont
and Scott model is successful in predicting
all the observed features of the correlation.
Finally, a procedure is outlined to calculate
the condensation rate based on present correlation
and bulk flow parameters.
