Kinetic modelling of nonequilibrium flows is described as it applies to hypersonic phenomenology. A Monte Carlo method is described for the study of species separation on shock wave fronts; a Particle in Cell with Monte Carlo Collisions (PIC/MCC) technique is described for the simulation of dust in plasma flows; modelling of nonequilibrium radiation in shock heated gases; implementation of slip models for the description of separation zones occurring in shockboudary layer interactions.

“…The full description of the model can be found in [11][12][13]25]. It is worth noting that what is presented here is actually a framework: different gas mixtures and chemical kinetics models can be studied by this code, with the possibility of studying both non-equilibrium and equilibrium spectral intensities of radiation emitted by shock-heated gases.…”

“…The first model, devoted to the study of non-equilibrium spectral intensity of radiation emitted by the shock-heated gases for comparison with available shock tube experimental data, has been developed in the Laboratory of Radiative Gas Dynamics in Moscow [11][12][13]. After an hybrid collisionalradiative (CR) model coupled to an Euler solver and a radiative transfer equation (RTE), used to investigate the dynamics of the electronic levels of the atoms behind a strong shock wave, has been developed in a joint collaboration between research groups in France and Belgium [14][15][16].…”

Abstract: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 the vibrational degree of freedom is presented first, and applied to the numerical rebuilding of experimental shock tube emission spectra. Next, an hybrid collisional-radiative model for ionized air is presented. This model consider the state-tostate approach for electronic states of atoms and the multi-temperature model for the vibrational populations of diatomic molecules in their ground electronic state. A radiative transport equation is also solved to determine radiative source terms in the kinetic scheme and the enthalpy production due to radiation. The third model considers the state-to-state collisionalradiative model of Jupiter's atmosphere, self-consistently coupled with the Boltzmann equation for free electrons and the radiative transfer equation for the radiation transport in one-dimensional slab geometry.

A physical model of multiple reflection of focused laser radiation propagating in narrow channels and slots is proposed to be applied in laser treatment of metals. Based on the laws of geometric optics, an algorithm for calculating the shape of the surface formed by interaction of laser radiation and metal with the use of the trajectory technique is proposed. The method used allows one to describe energy transfer inward the channel in simulation of laser-treatment processes (drilling, cutting, and welding). It is shown that the efficiency of multiple reflection is most significant in cutting thick materials with a large ratio of the plate thickness to the Gaussian beam width.
