An accurate and efficient radiation transfer model, based on the view-factor approach, is proposed for the reentry flowfield. The radiation transfer equation is coupled to the gasdynamic system of equations in order to describe the energy transfer in the absorbing and emitting air plasma in two-dimensional axisymmetric and three-dimensional geometries. A newly derived semi-analytical expression for the radiative flux density dramatically simplifies the calculation of the spectral and integral characteristics of the radiation flowfield in the axisymmetric geometry. The comparison with the ray-tracing method and tangent slab approximation revealed an asymptotic accuracy of radiation flux density.

“…Plasma inhomogeneities and radiation transport effects have previously been examined by Wester and Noll [22]. The evolution of laser-induced plasma has been studied by Casavola et al [23] and dynamics in laser-induced plasmas has also been investigated by Surzhikov et al [24]. Kinetic processes in laser-induced plasmas were also discussed by Pietanza et al [25].…”

a b s t r a c tWe report on efforts to perform theoretical modeling of the emission spectrum measured from a basalt sample. We compare our calculations with measurements that were made to provide standards for the ChemCam instrument on the Mars Science Laboratory. We find that to obtain good agreement between modeling and the measurement, it is necessary to determine atomic and ionic level populations via a multi-element approach in which the free electron density that is created influences all the species within the plasma. Calculations that consider each element separately are found to be in poorer agreement with the measured spectrum, indicating that the 'matrix effect' term often used to describe the influence of other species on the emission spectrum from a given element is due to the influence of the global electron density of the plasma. We explore the emission features in both the visible and near-infrared wavelength ranges, and also examine radiation transport effects for some of the most intense features found in the basalt spectrum. Finally, we also provide comparisons of the ChemCam measurement with new high-resolution spectral measurements.
