  • Worked examples are a necessary element to any textbook in the sciences, because they reinforce the theory (i.e. the principles, concepts and methods). Once the theory has been understood, well chosen examples can be used, with modification, as a template to solve more complex, or similar problems. This work book contains examples and full solutions to go with the text of our e-book (Heat Transfer, by Long and Sayma). The subject matter corresponds to the five chapters of our book: Introduction to Heat Transfer, Conduction, Convection, Heat Exchangers and Radiation....

  • As motive force of processes, heat must be transferred from one fluid to other, task that is performed by means of heat exchangers. From this point of view, heat exchangers represent an important element of thermal facilities that has substantially contributed to technical development of the society. Today it is impossible to imagine any branch of process engineering and energy technology without involvement of heat exchangers. Advanced models of these apparatus were proposed in the middle of the 18th century, while theoretical backgrounds have been completed a century later....

  • Heat transfer is a fundamental part of thermal engineering. It is the science of the rules governing the transfer of heat between systems of different temperatures. In thermodynamics, the heat transferred from one system to its surroundings is assumed as a given process parameter. This assumption does not give any information on how the heat is transferred and which rules determine the quantity of the transferred heat. Heat transfer describes the dependencies of the heat transfer rate from a corresponding temperature difference and other physical conditions....

  • Energy is defined as the capacity of a substance to do work. It is a property of the substance and it can be transferred by interaction of a system and its surroundings. The student would have encountered these interactions during the study of Thermodynamics. However, Thermodynamics deals with the end states of the processes and provides no information on the physical mechanisms that caused the process to take place. Heat Transfer is an example of such a process. A convenient definition of heat transfer is energy in transition due to temperature differences.

  • AIR-HEATING PROCESSES Air can be heated by burning fuel or by recovering waste heat from another process. In either case, the heat can be transferred to air directly or indirectly. Indirect air heaters are heat exchangers wherein the products of combustion never contact or mix with the air to be heated. In waste heat recovery, the heat exchanger is termed a recuperator. Direct air heaters or direct-fired air heaters heat the air by intentionally mixing the products or combustion of waste gas with the air to be heated. ...
