Résumé : Stability of self-similar hypersonic flows over a flat plate in presence of local thermodynamic equilibrium conditions is studied by means of linear Parabolized Stability Equations (PSE). A spectral collocation numerical method together with a finite difference-based marching scheme are used to solve the equations, while the gas mixture and transport properties are computed with a table look-up procedure. High temperature effects are found to destabilize the second Mack mode regardless of the adiabatic/isothermal wall condition considered. On the other hand, nonlocal effects how a Mach-dependence influence: stabilizing at lower Mach, while destabilizing at higher ones.
