The following problems are being solved in Department of Physical and Chemical Mechanics in the present time:

  • 2D and 3D radiative gasdynamics models of reentry of spacecrafts designed to study the planets of solar system and subsequent return to Earth are being developed. These models were implemented in the NERAT computer codes (Non-Equilibrium Radiative AeroThermodynamics) and are based on a system of Navier-Stokes equations, the physical and chemical kinetics of multicomponent gas mixtures and the selective transport of thermal radiation.
  • Software package for the calculation of nonequlibrium spectral radiation of shockwaves is being developed in the laboratory. The gas mixtures that correspond to the atmospheres of planets of solar system are being considered. The models being implemented in the package are based on the self-consistent calculation of gasdynamic parameters, nonequlibrium physical chemical relaxation processes behind the shockwave front, nonequlibrium chemical kinetics in a gas mixtures and nonequilibrium radiation in the conditions when the Boltzmann distribution of particles among the excited energy states of atoms and molecules is not valid. Systematic analysis of new experimental data on the nonequilibrium radiation of shockwaves in different gas mixtures is carried out.
  • Fundumental studies in the field of nonequilibrium statistical thermodynamics and radiation of multitemperature gas mixtures are being performed.
  • The computer platform ASTEROID (universal multimodule computer system), intended for the calculation of spectral optical properties of hot gases and low temperature plasma in the context of problems of aerospace industry. This computer system is based on the usage of ab-initio methods of classical and quantum mechanics.
  • Copmutational theoretical models of interaction of gas discharges and hypersonic gas flows are being developed.
  • Systematic studies in the area of aerothermodynamics of hypersonic flight vehicles are being carried out.
  • Computer models of combustion and detonation of experimental devices and astrophysical objects are being developed
