Heat exchangers are used to exchange heat among the fluids with different
temperatures. In the production and management of energy, 90% of the heat
energy used is transported through various types of heat exchangers. As gen-
eral equipment in processes, heat exchangers have a number of applications
in power plants, chemical industry, petroleum industry, food industry, aero-
and space industry, nuclear industry, and a lot of other industries. Since the
first oil crisis in 1973, more interest and emphasis have been put on energy
saving, effective utilization of energy, and looking for new energy sources.
As one of the main process equipment in most of energy utilization systems
and some process industries such as petrochemical industry, heat exchangers
have been intensively investigated in wide aspects including thermal perfor-
mance prediction, optimal design, structure improvements, enhanced heat
transfer techniques, dynamic response behavior, automatic control, network
synthesis, numerical simulation, experimental methods, manufacturing, and
development of new kinds of heat transfer surfaces and heat exchangers. In
the manufacturing industry, more efforts are focused even on reducing
material consumption for heat exchangers.
Because of the increasing demand for the theory, methodology,
and technology for heat exchanger design and operation, many textbooks, pro-
fessional books, and handbooks about heat exchangers have been published,
such as Fundamentals of Heat Exchanger Design by Shah and Sekulic (2003), Heat
Exchangers: Selection, Rating, and Thermal Design by Kakac et al. (2012), Dynamic
Behaviour of Heat Exchangers by Roetzel and Xuan (1999), Compact Heat
