Hydrodynamics of Gas Channel Formation.

Abstract

The hydrodynamic response of a gaseous medium to the passage of a series of brief, widely spaced, well collimated energy pulses (e.g., electron beam pulses, laser pulses, discharges, etc.) is studied. Fluid code simulations are reported over a wide range of parameters. Iterative analytic formulae are given for the density reduction profile resulting from each pulse. Shock production heating, as well as other dynamic effects, are included. (Author)
