The paper presents radiation models developed to investigate radiation in entry in Earth, Mars and Jupiter atmospheres. The capacity of ASTEROID computing code to simulate elementary radiative processes, calculate spectral and groups optical properties, and also solve simple radiative heat transfer problems is presented for Earth entry. The large number of… (More)

The paper presents three collisional-radiative models developed to investigate non-equilibrium chemistry and radiation in hypersonic shock tubes operating with different planetary atmospheres. An hybrid collisional-radiative model, employing the state-to-state kinetics of electronically excited states of molecules and the multi-temperature approximation for… (More)

a r t i c l e i n f o a b s t r a c t An efficient algorithm to calculate the contribution of electron–electron collisions in the Boltzmann equation for free electrons, in the two-term approximation is presented. The electron–electron collision term must be energy-conserving, while, due to non-linearity, commonly used algorithms do not satisfy this… (More)
