  • The first law of thermodynamics gives the quantiative relations between the internal energy of a system and the quantities of heat and work that the system exchange with surroundings. It express the conservation of energy. The first law of thermodynamics is true, but not enough ! Why ? Many thermodynamic processes which don’t violate the 1st law, but don’t happen in nature !

  • Chapter 6 - The second law of thermodynamics. In this chapter, the thermal energy reservoirs, reversible and irreversible processes, heat engines, refrigerators, and heat pumps are introduced first. Various statements of the second law are followed by a discussion of perpetualmotion machines and the thermodynamic temperature scale. The Carnot cycle is introduced next, and the Carnot principles are discussed. Finally, the idealized Carnot heat engines, refrigerators, and heat pumps are examined.

  • Combustion involves change in the chemical state of a substance from a fuel state to a product state via a chemical reaction accompanied by release of heat energy. Design or performance evaluation of equipment also requires knowledge of the rate of change of state. This rate is governed by the laws of thermodynamics and by the empirical sciences of heat and mass transfer, chemical kinetics and fluid dynamics. Theoretical treatment of combustion requires integrated knowledge of these subjects and strong mathematical and numerical skills.

  • The constitutive law of plastic deformation expresses the effects of material behavior and properties for stress analysis in the design of manufacturing technology and product service behavior, for materials testing, and for the maintenance of structural and machine components. The book represents the state of the art, but the editors do not rule out other concepts of constitutive laws. There are many different facets of the same problem and as many answers; the right one is the one that gives the most practical solution, the one that best serves the specific problem....

  • Progress of thermodynamics has been stimulated by the fi ndings of a variety of fi elds of science and technology. In the nineteenth century, studies on engineering problems, effi ciency of thermal machines, lead to the discovery of the second law of thermodynamics. Following development of statistical mechanics and quantum mechanics allowed us to understand thermodynamics on the basis of the properties of constituent molecules.
