Thermodynamic and mechanism

The actual steam rate is obtained by dividing the theoretical steam rate by the turbine efficiency, which includes thermodynamic and mechanical losses. Alternatively, internal efficiency can be used, and mechanical losses applied in a second step.

Thermodynamic and mechanical equilibrium on a curved vapor-liquid interface requires a certain degree of superheat in order to maintain a given curvature. Characteristics of homogeneous and heterogeneous nucleation can be estimated in the frame of classical theory of kinetics of nucleation (Volmer and Weber 1926 Earkas 1927 Becker and Doring 1935 Zel dovich 1943). The vapor temperature in the bubble Ts.b can be computed from equations (Bankoff and Flaute 1957 Cole 1974 Blander and Katz 1975 Li and Cheng 2004) for homogeneous nucleation in superheated liquids... 

It is possible that the volume is determined by a combination of thermodynamics and mechanics. An example is reaction in an elastic balloon. See Problem 2.20.

Equations 12 through 14 may be derived from thermodynamic and mechanical expressions for the transverse force and torque acting on a surface which intersects the interfacial region ( ). Moments of an isotropic pressure force and a surface tension acting at R are... 

From a thermodynamic and mechanical point of view, the glass transition, Tg, is one of the most important parameters for characterizing a polymer system [1-3,24,29,32,33]. Consequently, the determination of the Tg is usually one of the first analyses performed on a polymer system.

In this review, modem interpretations of the kinetics, thermodynamics and mechanisms of curing of epoxy oligomers with primary, secondary, and tertiary amines and their mixtures, as well as the structure of the resulting polymers are discussed. The effect of the structure of the reagents on their reactivity is analyzed. Kinetic peculiarities of the deep stages of the curing process are emphasized Problems to be solved in the future are formulated. 

Low-molecular-weight model compounds such as phenylglycidyl or other mono-glycidyl ethers as well as primary, secondary and tertiary amines have been used for the study of the kinetics, thermodynamics and mechanism of curing. To reveal the kinetic features of network formation, results of studies of the real epoxy-amine systems have also been considered. Another problem under discussion is the effect of the kinetic peculiarities of formation of the epoxy-amine polymers on their structure and properties. 

The thermomechanical data accumulated during the last years as a consequence of the improvement of the technique of deformation calorimetry contributed significantly to the understanding of thermodynamics and mechanisms of the reversible deformation of polymers in the glassy, semicrystalline and rubbery state.
