The paper offers the equation of state (EOS) for the description of pressures and internal energies in a wide range of densities and temperatures. The thermal components of pressure and energy are represented by tables in a uniform logarithmic net with the bicubic node interpolation. The potential components are represented by the cubic spline on a uniform grid, which density is higher than the normal one. To calculate pressures and energies behind the tabulation domain, simple extrapolation formulas are suggested. The GLOBE equation of state can be used in codes for the continuum dynamics simulation. The equation of state functionality is demonstrated by the example of describing the properties of copper.

The paper describes the techniques and results of the numerical simulation of turbulent mixing processes for supersonic flows in channels of mixing gasdynamic lasers. Turbulent flows of a nonequilibrium gas mixture are described by the parabolic NavierStokes equations and kinetic vibrational relaxation equations. Both algebraic and differential models of turbulence are used to find the turbulent viscosity value. The equation system is numerically integrated with the McCormack finitedifference method using a Lagrangian grid. For various models of turbulence, the dependence of the calculated results on the difference grid in use and model parameters is analyzed. The calculated results and experimental values of the magnification coefficient and energy sampling are compared.
