Özet
In this study, with the effect of baffle cut,
spacing, tube arrangement, and flow velocities on
the heat transfer coefficient of a shell and tube heat
exchanger with the aim of optimizing the design
parameters. The study is concerned with propylene
glycol-water systems and includes thermal
calculations and design parameters. One particular
case studied is that of cooling propylene glycol from
90°C to 70°C at a flow rate of 55 kg/s with water as
coolant. The heat exchanger was of E-type with 364
tubes, nominal diameter 700 mm, tube length 6.6 m.
The overall heat transfer coefficient was estimated
to be 600 W/(m²°C); it was accepted to be 585.77
W/(m²°C). Baffle design was based on the Kern
method with a 500 mm spacing and a 25% cut
