Abstract
An exprimental study on the effect of vapour speed
on the heat transfer coefficient during condensation
was undertaken. A double pipe horizontal condenser
type was used where condensation occurs on the external
surface of the inner tube.
An experimental set-up was designed and fabricated
for this purpose. Test runs were carried on this set-up.
The results obtained were analyzed to study the effect of
the vapour speed on the beat transfer coefficient and
obtain the relationship between the dimensionless groups
which discribe tbis phenomenon.
Another test condenser was designed and fabricated
similar to the previous one but in other dimensions.
Additional test runs were carried on it.
The runs covered vapour speed value of J.J (m/s)
to 8 (ml s) .
The effect of vapour speed on the condensation number
and the condensate film Reynolds number was also
investigated.
Mathematical relationships were obtained to relate
all of these variables to the vapour speed in which the
correlations between Rev, Pr, Nu, Co, and Ref were
presented.
