Compressibility effect in hypersonic boundary layer with isothermal wall condition
Compressibility effect in hypersonic boundary layer with isothermal wall condition
Helmholtz decomposition is applied to investigate the compressibility effect in hypersonic turbulent boundary layers. The dilatational component of flow plays an important role in the near-wall region, while the solenoidal component is dominant far from the wall. The cold wall condition significantly enhances the compressibility, and especially enhances compression motions …
