Abstract

Numerical simulations of turbulent compressible flow interactions with an oncoming shock are performed using Morphing Continuum Theory. Governing equations are presented and discussed for their relevance to turbulent compressible flows. Material parameters used to successfully generate turbulent boundary layers are employed. A turbulent kinetic energy spectrum is generated for low-Re turbulence and interacts with a bow shock around a cylinder. Kinetic energy spectra are recorded before and after interacting with the shock wave. The excitation of low-wave number eddies is observed, and an inverse energy cascade from turbulent eddies to translational motion is also found. Absolute rotation, characterizing eddy structures, is amplified considerably behind the shock. This result indicates that the Navier-Stokes equations do not apply after the shock. MCT’s success with turbulent interactions with the shock, and its previous success with incompressible turbulent boundary layers, imply that future progress can be made with regards to shock-turbulent boundary layer interactions.
