| Summary: | 碩士 === 國立屏東科技大學 === 機械工程系 === 92 === This thesis aims at discussing about the heat transfer and
effectiveness of a heat-exchanger that is one of the equipments
required to operate a steam power plant.
The heat-exchanger in this thesis is used to cool partial ci-
rculating water with sea-water；therefor,it can be called a 〝coo-
ler〞.Although this equipment only does the heat exchanging,but
it affects the volume of electric generator power output.So th-
at it should be treated as a key-unit in a power generation sys-
tem.
Bell-Delaware method was taken to identify those parameters
which may have effects on the effectiveness of the Shell-and-Tu
be type heat-exchangers.Many numerical experiments are performed
,parameters have been investigated includes:the sea-water inlet
temperature,tube materials,tube diameter,buffle-cut percentage,
and buffle pitch.Result shows that the sea-water inlet tempera-
ture is the key parameter which will have the most prominence e-
ffect on the effectiveness.
