Methods for the analysis of high-pressure, high-enthalpy constricted arc heaters
Abstract
This paper describes the development of a computer program for predicting the performance and operating characteristics of a high-pressure (150-200 atm), high-enthalpy (6000-8000 Btu/lbm) constricted arc heater. The currently available code of Watson and Pegot, which solves the equations governing the thermodynamics and fluid mechanics of a constricted arc, was extended to the high pressure regime of interest. A new radiation model accounting for self-absorption was incorporated, and the turbulence model was upgraded. State-of-the-art radiation, thermodynamic, and transport property tables were generated for air. The new code was successfully validated through comparisons with available high-pressure (up to 100 atm) arc heater bulk enthalpy and voltage drop data.
