A SUMMARY OF CALCULATIONS OF CHEMICAL AND FLUID DYNAMIC PARAMETERS IN THE SAPAG FACILITY.

Abstract

Calculations are presented for the trajectories and burnup times of submicron-size particles in a shock tube where the local flow is free molecular with respect to the particles. Materials ranging in thermodynamic properties from teflon to graphite are treated. It is shown that the burnup times are short compared to characteristic shock tube testing times, and that the small (0.2 micron diameter) particles accelerate to the local free stream velocity almost instantaneously. An operating map is presented for calculating the acceleration time of particles in a shock tube where the local flow is continuum with respect to the particles. (Author)
