Nonequilibrium ionization phenomena behind shock waves

Abstract: Articles you may be interested inOn core compressibility of sandwich composite panels subjected to intense underwater shock loads J. Appl. Phys. 115, 024905 (2014) Abstract. An accurate investigation of the behavior of electronically excited states of atoms and molecules in the post shock relaxation zone of a trajectory point of the FIRE II flight experiment is carried out by means of a one-dimensional flow solver coupled to a collisional-radiative model. In the rapidly ionizing regime behind a strong shock wa… Show more

“…Several different mechanisms are involved in the meteoroid ablative mass loss; the prevalence of specific ablation mechanisms is a function of meteoroid mass, velocity, composition and altitude (Bronshten, 1983). High energy collisions with the local atmosphere involve the exchange of translational, rotational, and vibrational energy and lead to excitation, dissociation and ionization of both incident atmospheric molecules and ejected meteoric atoms (Bauer, 1990;Dressler et al, 2001;Zinn et al, 2004;Panesi et al, 2011). Depending on the meteoroid velocity, the kinetic energies imparted collisionally to ablated meteor atoms may exceed several hundred electron volts (eV), while the initial kinetic energy of any free electrons may approach 10 eV (Baggaley, 1980;Hocking et al, 2016b).…”

“…These collisions lead to internal energy exchange between translational and internal degrees of freedom and result in excitation, dissociation, ionization and radiation. In the compressed shock layer, the excess internal energy in turn facilitates various non-equilibrium and hyperthermal chemical reactions (Berezhnoy and Borovička, 2010;Panesi et al, 2011;Brun, 2012) further down in the reactive high temperature meteoroid flow fields (Zel'dovich and Raizer, 2002;Anderson, 2006;Brun, 2009).…”
