The results of a new experimental campaign on a sharp double cone model placed within Alta’s HEAT pulsed hypersonic tunnel in a Mach 9 non-equilibrium air flow are presented. The model geometry has cone semiaperture angles of 25 and 55 degrees, in order to allow the comparison with other literature experiments and simulations; the maximum diameter is of 70 mm. The model is instrumented on one side with 10 fast pressure sensors and 7 thermocouples, while the other side is left untouched in order to perform fast infrared thermography. The nozzle was realized and characterised in detail in order to provide good quality data regarding the free stream for the numerical reconstruction. The results allowed to compare surface pressure, temperature and heat flux as well as the extension of the recirculation zone with previous literature results

Abstract

The results of a new experimental campaign on a sharp double cone model placed within Alta’s HEAT pulsed hypersonic tunnel in a Mach 9 non-equilibrium air flow are presented. The model geometry has cone semiaperture angles of 25 and 55 degrees, in order to allow the comparison with other literature experiments and simulations; the maximum diameter is of 70 mm. The model is instrumented on one side with 10 fast pressure sensors and 7 thermocouples, while the other side is left untouched in order to perform fast infrared thermography. The nozzle was realized and characterised in detail in order to provide good quality data regarding the free stream for the numerical reconstruction. The results allowed to compare surface pressure, temperature and heat flux as well as the extension of the recirculation zone with previous literature results
