Theoretical Investigation of Thermo-hydraulic characteristics of Shell and Tube Heat Exchanger
Abstract
Shell and tube heat exchangers (STHX) are still a popular
choice in many industrial applications because of their
substantial heat transfer area to volume and weight ratios and
ability to meet nearly any service need. They're commonly
found in nuclear power plants, steam generators, and feedwater
heaters. Because of their excellent effectiveness, STHXs are
being used in a growing number of industrial procedures. The
aim of the present investigation is to theoretically calculate the performance parameters of the STHX at different conditions.
According to the theoretical study, the heat exchanger's
effectiveness declines as the hot fluid's inlet temperature rises. At a constant value of Reynolds number for the hot fluid, the effectiveness is maximum for Reynolds number of 1000 for the cold fluid. As the inlet temperature of the hot fluid rises, the heat exchanger's performance rises as well. It was also discovered that as the inlet temperature of the hot fluid
increases, the tube side pressure drop increases at a constant
value of the Reynolds number of hot fluid.
