Figure 15.1 shows families of solutions to the model problem for different values of X and different initial conditions. The family of solutions can be thought of as a manifold of solutions, all of which, regardless of the initial condition, tend toward the slowly varying y = t2 + 1 solution. In chemical kinetics, the behavior illustrated in Fig. 15.1 is exhibited by certain species, like the free radicals. After initial very rapid transients such as a combustion ignition, the free-radical concentrations often vary slowly, with their behavior controlled by steady-state or partial-equilibrium conditions. The faster the characteristic scales, the more rapidly the fast-time-constant species come into equilibrium with the major species (i.e., approach a slowly varying solution).

The combustion of coal and carbon particles has been extensively studied by Hottel and associates (5G, 10G, llfi). Individual particles of coal experience three periods in their combustion—ignition, distillation and combustion of volatile matter, and combustion of the fixed carbon. A discussion of the laws of particle distributions is included (6Cf). 

Besides the combustible consumable cartridge cases, other items of ammunition made of combustible or consumable materials have been developed. For example, a combustible igniter tube, developed at PicArsn, is discussed in Ref 19 and development 0f combustible primers is described in Refs 7 9- The last two refs are conf and were not used as sources of info (See also Cartridge, Combustible, in Vol 2,p C80-L)...

We find an analogous expression, in which the value of the constant in (11) is expressed in terms of the combustion heat, specific heat, and the combustion, ignition and initial temperatures, in the work of Holm [12], who constructed the thermal balance of a hemispherical flame, with the diameter of the hemisphere taken equal to the tube diameter. 

Modem diesel fuel can be produced from sources other than petroleum. Recently, attention has been focused on biodiesel. This is a cleaner-burning fuel made from natural and renewable sources such as vegetable oils. Just like petroleum diesel, biodiesel can operate in combustion-ignition engines. Essentially no engine modifications are required, and also biodiesel maintains the payload capacity and range of diesel.

Plastic characteristics related to their combustion are ignition and flash point, thermal conductivity, specific heat capacity and exothermic heat of combustion. Ignition occurs when a sufficient amount of combustibles (gases or liquids) are produced. The combustion mechanism is complex and involves reactions between radicals resulting during plastic degradation [120].
