Abstract
Heat exchangers with one shell pass and n tube passes
are often referred to as 1-n exchangers. The heat transfer
literature contains many references to studies of 1-n
exchangers when n is even but apparently, other than a
single study and some work pertaining to the 1-3 exchanger
at the Naval Postgraduate School, little work has been done
with respect to the 1-n exchanger when n is odd. This
thesis expands upon the study of 1-n exchangers with n being
odd.
While a completely closed form solution was found to be
unfeasible, a polynomial approximation has been developed
that yields the effectiveness (e) of the two possible
arrangements of the 1-5 exchanger as a function of the
capacity rate ratio (R) and the number of transfer units
(N(tu) ). This will enable the analyst to consider exchangers
where the inlet to and outlet from the tubes are at opposite
ends of the exchanger.
