Studying the Effects of Nanofluid as a Coolant Essay

Satisfactory Essays

1.1 Problem Statement
The whole outline of this project is to investigate the effect on heat transfer rate in a shell and tube heat exchanger when nanofluids are used as coolant (cooler medium). Computational Fluid Dynamics aids the research due to the complexity involved such as the flow structure and temperature distribution.

1.2 Significance of the Study
The main focus of this project is to study the effects of varying nanofluids as coolant on heat transfer rate using CFD with constant shell and tube heat exchanger model. I am pursuing this study to find more efficient way of heat removal using nanofluids as the cooling medium. All leakage and bypass stream in the heat exchanger do not exist or are negligible in this …show more content…

Shell and tube heat exchanger are usually used for higher pressure applications up to 552 bars.

2.2 Shell and Tube Heat Exchanger
Shell and tube heat exchangers are probably the most widespread and commonly used basic heat exchanger configuration used in the process industries. This is because shell and tube heat exchanger provides a larger ratio of heat transfer area to volume and weight. Its provide this surface in a form which is relatively easy to construct in a wide range of size and which is mechanically rugged enough to withstand normal shop fabrication stresses, shipping and field erection stresses, and normal operating conditions. Moreover there are many medication of the basic configuration is available to solve special problems. Those components that most subject to failure (gaskets and tubes) can be easily replaced and cleaned. Finally, good design methods exist and the expertise and shop facilities are available throughout the world.

2.2.1 Shell and Tube Exchanger: Geometric Terminology
The vital components of a shell and tube exchanger are shown in Figure 2 a, b and c and described in Table 1. Figure 2. Type BEM, CFU and AES exchangers.© 1988 by Tubular Exchanger Manufacturers Association.
