Size parameter particles

In Table 9.1, in the third column, the relation between /B and the particle size parameters (second column), corresponding to, and including, equation 9.1-27, is given for each shape. Similarly, in the fourth column, the relation between t and /B, corresponding to, and including, equation 9.1-28 is given. 

The conditions in the reaction zone determine the release rate of the N-precursors HCN and NH3 [11], Among these conditions are the properties of the fuel (e.g., N-content and particle size), parameters related to the combustion front (temperature and propagation velocity) and the gas composition in and directly above the combustion front. As the prediction of the mass fractions of the N-precursors is important for the final goal of this research, i.e., the prediction of NO formation of the complete furnace, a model is needed in which all these conditions are represented. 

The absorption and scattering efficiencies do not show the same dependence on the particle size parameter (3.

Figirre 2 depicts all norrzero elements of the reflection matrix in the doublescattering approximation for a semi-infinite layer composed of identical spherical particles. The particle size parameter is x = Ind X = 3, where d is the particle radius, and the particle refractive index is fh = 1.35+ 01. The resrrlts are shown for different values of the filling factor (packing derrsity) = nari / 3. ... 

Figure 5. Surfaces of constant phase and directions of vectors E (sum of the incident and scattered waves) in the close vicinity of a spherical particle. The incident wave propagates along the Z-axis (indicated by the wave vector k) and is polarized along the X-axis. The particle size parameter is x =4 and the refractive index is fh = 1.32 + 0.05 .
