Stability of combustion

When one considers the potential high-energy release on rupture of a carborane unit, together with the thermodynamic stability of combustion products, it is hardly surprising that there is a body of literature that reports on the use of carbo-ranes within propellant compositions. Their use in energetic applications is to be expected when the enthalpy of formation (AH/) data for the products of combustion for boron are compared to those of carbon. Thermodynamic data for the enthalpy of formation of o-carborane and of typical boron and carbon combustion products is shown in Table 4. Measurements of the standard enthalpy of combustion32 for crystalline samples of ortho-carborane show that complete combustion is a highly exothermic reaction, AH = — 8994 KJmol. ...

The stability of combustion wave propagation is an important factor in determining the quality of materials produced by CS. To produce uniform product, a stable combustion regime is desired. Furthermore, it is also important to know the boundaries where combustion, stable or unstable, can propagate.

The decrease of the atmospheric pressure decreases the stability of combustion on the contrary, the increase of the pressure increases the stability. Therefore firework pieces must be constructed sp that the burning pressure increases as far as possible. This is especially important in the case of ignition. For example, in Fig.28 A is more ignitable than B, when they are moving in high speed. 

This chapter reports experimental and analytical results for pulsed control of combustion instabilities at both fundamental and subharmonic frequencies. Two suites of control algorithms have been developed one based on least-mean-square (LMS) techniques that is suitable for inner-loop stabilization of combustion instabilities, and one bcised on direct optimization that can be used either for stabilization or outer-loop optimization of combustion process objectives, such as flame compactness or emissions.
