Abstract

The exchange of heat is one of the most important processes in the chemical industry and the Shell and tube heat exchanger is the major equipment used to transfer heat from one medium to another. This research project work on the Computer Aided Design (CAD) of shell and tube heat exchanger with double passes aims to provide an easy way to design shell and tube heat exchangers. A case study question was given and all the necessary calculations in the thermal design are carried out using Kern’s method of heat. exchanger design. The thermal design is then used as a guide to the computer aided design using computer codes. The computer software program used is the most recent version of Visual Basic called Visual Basic NET (VB.NET) because of its numerous advantages over the other software programmes. The result gotten from the computer aided design was compared to the result from the thermal design. The computer aided design software was equally used to test other

1.3 SIGNIFICANCE OF THE STUDY

Anyone who wants to use a heat exchanger faces a fundamental

challenge, fully defining the problem to be solved which requires an

understanding of the thermodynamic and transport properties of

fluid. Such knowledge can be combined with some simple

calculations to define a specific heat transfer problem and select an

appropriate heat exchanger.

Heat exchangers serve as straight forward purpose controlling a

system’s or substance’s energy. Although there are many different

sizes, levels of sophistication and types of heat exchangers, they all

use a thermally conducting tube or plate to separate two fluids

such that one can transfer thermal energy to the other.

This study thereby necessitates the need for the design and

development of software for which will lead to near maximum

performance of a heat exchanger.

Finally, the data obtained from this procedure shows that a one

shell-pass and two tube-pass heat exchangers is more efficient than

most heat exchangers in fluids thermal conductivity and transfer

combustion.
