The shell and tube heat exchanger is the major equipment used to transfer heat from one medium to another. This research work on the Computer-Aided Design (CAD) of shell and tube heat exchangers
Mar 26, 2018 · This is a two-pass exchanger where fluid enters through one side, travels the entire length of the exchanger and doubles back around, leaving through a different outlet on the same side. The two passes are separated by a longitudinal baffle that spans the majority of the length of the shell, but ends before it reaches the far tubesheet. Numerical Investigation on Double Shell-Pass Shell-and
Oct 01, 2018 · In this paper, double-tube-pass shell-and-tube heat exchanger (DTP-STHE) is proposed to improve the recovered heat quality from the point of exergy analysis. Results reveal that the recovered heat quality in DTP-STHE is almost twice as that in single-tube-pass shell-and-tube heat exchanger (STP-STHE). Shell and Tube Heat Exchangers - H&C Heat TransferThe shell-and-tube heat exchanger is by far the most common type of heat exchanger used in industry. It can be fabricated from a wide range of materials both metallic and non-metallic. Design pressures range from full vacuum to 6,000 psi. Design temperatures range from -250oC to 800oC.
As you can see, in a 1-2 heat exchanger, the tube-side fluid flows the entire length of the shell, turns around and flows all the way back. It is possible to have more than two tube passes. Multiple shell passes also are possible, but involve fabrication that is more complex and is usually avoided, if possible. Single, double or triple pass cooling - what's the In such instances 2-pass heat exchangers are an ideal solution, as they feature inlet and outlet water connections on the same end cover, so the cooling water enters and leaves the heat exchanger in the same location. 2-pass heat exchangers are also capable of handling the higher water velocities found in marine cooling applications.
