본문내용

Shell & Tube Heat Exchanger
Shell side : Saturated Vapor(100 ˚C) → Saturated Liquid(100 ˚C)
Tube side : cooling water 20˚C → 70 ˚C
Tube diameter : ¾ in
Effect of tube wall is negligible

※ Shell & Tube Heat Exchanger
The most versatile type of heat exchanger
Shell & tube heat exchangers provide relatively large ratio of heat transfer area to volume.
They can be easily cleaned
They are used in process industries, in conventional and nuclear power stations, steam generators, etc
They are used in many alternative energy applications including ocean, thermal and geothermal

5) Heat transfer coefficient outside tube(ho)
assume N=200,

6) Overall heat transfer coiefficient(U)

7) Effectiveness-NTU-(1)
The Number of Transfer Units (NTU) Method
- used to calculate the rate of heat transfer in heat exchangers
- when there is insufficient information to calculate the LMTD.
The effectiveness( )
- the ratio between the actual heat transfer rate
and the maximum possible heat transfer rate
