A shell and tube heat exchanger is a class of heat exchanger designs. It is the most common type of heat exchanger in oil refineries and other large chemical processes and is suited for higher-pressure applications. As its name implies, this type of heat exchanger consists of a shell (a large pressure vessel) with a bundle of tubes inside it. One fluid runs through the tubes, and another fluid flows over the tubes (through the shell) to transfer heat between the two fluids. The set of tubes is called a tube bundle and may be composed of several types of tubes: plain, longitudinally finned, etc. Two fluids, of different starting temperatures, flow through the heat exchanger. One flows through the tubes (the tube side) and the other flows outside the tubes but inside the shell (the shell side). Heat is transferred from one fluid to the other through the tube walls, either from the tube side to the shell side or vice versa. In this model, the User can assign the following:
1-Cold side temperature, oC, and flow rate (water).
2-Hot side temperature, oC, and flow rate (water steam).
3-Area, m2, tubes diameter, m.
4-NTU, Cmin, Cmax, ...
8-The model flowchart in PNG and PDF files.
**MatLab-SimuLink should be used to run the model.
