| dc.description.abstract | Eventually, economics plays a key role in the design and selection of heat-exchange
equipment, and the engineer should bear this in mind when embarking on any new heat
transfer design problem. The weight and size of heat exchangers used in space or
aeronautical applications are very important parameters, and in these cases cost
considerations are frequently subordinated in so far as material and heat exchanger
construction costs are concerned; however, the weight and size are important cost factors
in the overall application in these fields and thus may still be considered as economic
variables The primary modes of heat transfer are conduction and then convection. This is
not to imply that radiation is not important in heat exchanger design.
Heat exchanger is equipment used to transfer heat from one fluid to another. It has
extensive domestic and industrial applications. Extensive technical literature is available
on heat exchanger design, operation and maintenance, but it is widely scattered throughout
the industrial bulletins, industrial design codes and standard, technical journals, etc. The
purpose of this book chapter is to consolidate into basic background and concepts design
of heat exchangers, operation, cleaning and green technology maintenance on heat
exchanger closely related to the industrial practices. A fin-and-tube heat exchanger model
is presented in this paper. It uses empirical heat transfer and flow friction correlations
identified in the literature. The model structure, its range of validity and accuracy are
described in detail. | en_US |
