Resumo
The radiation characteristics of shock-heated argon are measured in the shock-wave velocity range of 4.5 to 7.8 km/s at gas pressures ahead of the shock wave front of 0.25, 1.0, and 5.0 Torr. Time-integrated sweeps of radiation and the time dependences of the radiation intensity of shock-heated argon at the wavelength of 420 nm are obtained in absolute units. The results of direct statistical simulation by the Monte Carlo method of radiation-chemical processes in the argon behind the front of a strong shock wave are presented. The model takes into account the processes of excitation and ionization of an atom by electron impact, emission and absorption for a discrete spectrum, bremsstrahlung, photoionization, and photorecombination, as well as the broadening of atomic lines. The experimental and calculated data are compared.
