Behavior of high-pressure air in critical-flow through nozzles

Abstract

This paper reports mass flux for air in critical-flow through nozzles that have been calculated using a fundamental equation for air expressed in terms of the Helmholz energy. Flux values are reported for plenum pressures up to 3.4 x 107 N/m2, and temperatures that range from 225 K to 800 K. Critical flow factors are also reported for this pressure and temperature range. The results agree very well with those previously calculated for lower pressures, and whose values have been well established experimentally. The present results represent an extension of critical flow factors to much higher plenum pressures and temperatures.
