An extension of the recycle-rescaling inflow boundary conditions for high-enthalpy multi-component hypersonic turbulent boundary layers is proposed in this work. The new boundary condition is tested using a Mach-10 zero-pressure-gradient boundary layer, which has previously been analyzed using direct numerical simulations that involve the entire turbulence transition.

Abstract
An extension of the recycle-rescaling inflow boundary conditions for high-enthalpy multi-component hypersonic turbulent boundary layers is proposed in this work. The new boundary condition is tested using a Mach-10 zero-pressure-gradient boundary layer, which has previously been analyzed using direct numerical simulations that involve the entire turbulence transition. The results of this analysis show that the new boundary condition allows a significant reduction in computational cost compared to the reference calculations, while preserving the maximum error for thermochemical and hydrodynamic fields below 5%.File in questo prodotto:
