Self dissipative

In this case the flucPiation-dissipation relation, ( A3.2.21T reduces to D = IcTa. It is also clear that GE = (A + S)/Mlct which is not self-adjoint. [Pg.700]

Certain materials which are generally considered to be stable at ordinary temperatures can inflame even in tlie absence of normal ignition sources. Such spontaneous combustion results from exotliermic autoxidation when the heat liberated exceeds that dissipated by the system. Materials prone to self-heating are listed in Table 6.7. In most cases, such fires involve relatively large, enclosed or thermally-insulated masses, and spontaneous combustion usually occurs after prolonged storage. [Pg.185]

Short-time Brownian motion was simulated and compared with experiments [108]. The structural evolution and dynamics [109] and the translational and bond-orientational order [110] were simulated with Brownian dynamics (BD) for dense binary colloidal mixtures. The short-time dynamics was investigated through the velocity autocorrelation function [111] and an algebraic decay of velocity fluctuation in a confined liquid was found [112]. Dissipative particle dynamics [113] is an attempt to bridge the gap between atomistic and mesoscopic simulation. Colloidal adsorption was simulated with BD [114]. The hydrodynamic forces, usually friction forces, are found to be able to enhance the self-diffusion of colloidal particles [115]. A novel MC approach to the dynamics of fluids was proposed in Ref. 116. Spinodal decomposition [117] in binary fluids was simulated. BD simulations for hard spherocylinders in the isotropic [118] and in the nematic phase [119] were done. A two-site Yukawa system [120] was studied with... [Pg.765]

Self-Organization of Materials Into Microscale Patterns by Using Dissipative Structures... [Pg.187]

The flow of matter and energy through an open system allows the system to self-organize, and to transfer entropy to the environment. This is the basis of the theory of dissipative structures, developed by Ilya Prigogine. He noted that self-organization can only occur far away from thermodynamic equilibrium [17]. [Pg.189]

Viscous iiquids have difficuity in dissipating the heat produced by the beginning of a reaction. The heat can thus cause the substance to reach a temperature that is sufficient to provoke its self-ignition. It occurs in a lot of reactions involving glycerol with potassium permanganate or sodium hydride. [Pg.153]

Dissipative self-organisation, for example in evolving systems. [Pg.244]

Systems with dissipative self-organisation are important for processes which lead to biogenesis. These are open systems, the internal state of which is dominated by a disequilibrium far away from the equilibrium state. [Pg.244]

Processes which generate heat in organic materials are reviewed. At ordinary temperatures, respiration of living cells and particularly the metabolism of microorganisms may cause self-heating, while at elevated temperatures pyrolysis, abiotic oxidation, and adsorption of various gases by charred materials drive temperatures up whenever the released heat is unable to dissipate out of the material. The crucial rate of pyrolytic heat release depends on exothermicity and rates of the pyrolysis process. [Pg.429]

Figure 4 shows the results. Above 200"C, the dashed line reflects heats of pyrolysis according to Equation 2 and Figure 3, while the more realistic, full line is based on heats which approach zero at 300 C. According to the figure, heat release peaks between 130 and 230 C. Since heat dissipates out of self-heating materials in proportion to temperatures above ambient, and at 230"C the dissipation should exceed the dissipation at 130 C by a factor of two, the most rapid pyrolytic self-heating can be expected between 120 and 170 C. [Pg.444]
