Abstract
Computational studies of the shock focusing process after reflection from an axisymmetric parabolic wall were conducted considering molecular vibrational energy relaxation. Nitrogen was used as a test gas. From the numerical data, the amplification of physical quantities at the gasdynamic focus was calculated for different incident shock Mach numbers. The pressure amplification and temperature at the gasdynamic focus become lower than those in the vibrationally frozen case. Such phenomena become more and more conspicuous with an increase in the incident shock strength and the depth of the reflector.
