A Performance Study of a Piston Compression Shock Tunnel

Abstract

A theoretical study of a high performance piston compression tailored mode reflected shock tunnel, designed to achieve re-entry flow simulation, has been carried out. The designed tunnel supply conditions were pressures varying from 2000 to 5000 atm at temperatures from 6000 to 12,000K. The pressures and temperatures involved in the study were high enough that imperfections in the equation of state covering both dense gas effects and internal energy modes were required to be assumed. Similar running times as in conventional shock tunnels have been shown to be achieved at the design performance with relatively lowly stressed tube extensions. Helium is shown to be a more efficient driver gas than hydrogen in piston compression operation in terms of both performance and running time.
