Effect of linear-anisotropic scattering on ir-signatures from cylindrical plumes

Research output: Contribution to conferencePaperpeer-review

Abstract

The corresponding integral form of the equation of radiative transfer in absorbing, emitting, linear-anisotropic scattering media is used to compute the spectral hemispherical and the spectral plume emissivities of a one-dimensional cylinder. The solution is based on using power series representations of the temperature and incident radiation profiles. The expansion coefficients for the temperature are assumed known, whereas the expansion coefficients for the incident radiation are solved for by the application of a collocation strategy based on the zeroes of the Chebyshev polynomials. As the method of solution yields highly accurate results, it is employed to study the interaction between an absorbing/emitting gas phase and an absorbing/emitting/scattering particle phase. The numerical results indicate that the plume emissivity is enhanced by as much as 20 per cent by the presence of purely scattering particles.
