Comparison of scattering behaviour for spherical and non-spherical particles in pulverized coal combustion

The calculations reveal a deviation in scattering and absorption efficiencies below 10 % due to non-sphericity for all particles. For the scattering phase function, the deviation is on the order of 10 %. It strongly varies depending on the particle type under investigation. Nevertheless, Mie-theory can correctly predict trends. Taking into account several uncertainties in the input parameters for scattering calculations, Mie-theory can be applied in the prediction of scattering and absorption properties in numerical simulations of coal combustion.
