Collisional Momentum and Energy Transfer Rates for Two-Fluid Nuclear- Burst Simulations
Abstract
A compendium of cross sections is given for atomic collision processes relevant to high-altitude nuclear burst. Experimental or theoretical cross sections for elastic scattering, inelastic scattering, and charge exchange in ion-neutral and neutral-neutral collisions and for elastic scattering in electron-neutral and electron-ion collisions are given for atmospheric species in the velocity range of 10,000 to 10 to the 9th power cm/sec. The electrical resistivity and the rates of momentum and heat transfer between the ion fluid and the neutral fluid are obtained from these cross sections for the case that the particle velocity distribution of each species is Maxwell-Boltzmann. The coefficients for these quantities are given graphically and numerically for temperatures in the range 0.01 to 500 eV. A summary shows how to use these data in two-fluid magnetohydrodynamic simulations of high-altitude nuclear bursts at times subsequent to one second.
