Comparison between Probe Stagnation Point Heat Flux Measurements and Correlation Formulas in SCIROCCO Plasma Wind Tunnel Tests

摘要

A large part of the SCIROCCO Arc Heater Performance Map has been investigated. The heat flux measurements at the stagnation point of the facility Calibratio Probe have been used to find an experimental fit. Such a formula has been compared with the predictions of the De Filippis-Serpico equation and the well known Fay-Riddell formula. Finally the experimental fit has been also compared with the Sagner-Verant formula obtained at the ONERA F4 hypersonic plasma wind tunnel.
