CALORIMETRIC INVESTIGATION OF GAS ENTERING THE NOZZLE OF A LOW-DENSITY HIGH-VELOCITY WIND TUNNEL

Abstract

The impetus for conducting a calorimetric investigation of an arc- heater generated flow entering the diverging section of a supersonic nozzle was initiated by construction, at the University of Illinois, of a low-density, hypervelocity wind tunnel, consisting of an arc-heater, stilling chamber, supersonic nozzle, test chamber, adjustable diffuser, and a steam-ejector vacuum pump. All major components of the tunnel were tested separately. A total calorimeter was designed and built to establish by direct measurement the stagnation enthalpy at the nozzle throat.
