CONDENSATION ON A THIN FILM FLOWING OVER AN ADIABATIC SPHERE
Аннотация
A binary boundary layer approach is used to
analyze the condensation of a saturated vapor on
a thin laminar film of either the same or a
different liquid flowing over a sphere. It is
assumed that the condensate forms a continuous layer
on the film. Thus, while the analysis deals with a
vapor condensing on an immiscible film, it also
applies to a vapor condensing on its own liquid.
Expressions are presented for the average Nusselt
Number over the segment of a sphere where a thermal
boundary layer is penetrating the film and for the
degree of utilization of the cooling capacity of
the film as a function of the important non-dimensional
parameters. Comparison with published
data confirms the applicability of the result.
