DNS of turbulence backscatter in a laboratory-scale swirl stabilized aero-combustor
Classical theories of turbulence suggest that the kinetic energy cascade in nonreacting flows has a net transfer of energy from large to small scales. However, previous studies demonstrated that the thermal expansion of premixed flames can reverse the flux of kinetic energy through the injection of…
