| Description |
The most important parameter in low-density arc-heated ows for atmosphere entry simulations is the centerline totalenthalpy Hcl which is strictly related to the average total enthalpy Hne (bulk enthalpy at nozzle exit). In this paperthe "sonic ow method" widely used for Hcl calculation in mono-atomic and diatomic molecules gas mixtures, has beenextended to polyatomic molecules gas mixtures. By means of a reduced-scale arc-jet facility and using Nitrogen N2 as hotfeeding gas, three mixtures were investigated by adding cold gases like O2, CO2 and CH4 through a mixer just before thenozzle. Using bulk enthalpies ranging between 5 and 30 [MJ=Kg] the calculated enthalpy ratios were Hcl=Hne = 1:38for N2
