The structure of reacting compressible homogeneous turbulent shear flow is examined via data generated by direct numerical simulations DNS. The reaction is modeled as one-step, exothermic, irreversible, and Arrhenius type. The effects of reaction are studied by decomposing the velocity field into its solenoidal and dilatational parts. The heat of reaction significantly enhances the dilatational kinetic energy, while it reduces its solenoidal counterpart. The solenoidal and dilatational large scales kinetic energy and small scales viscous dissipation anisotropies are investigated for cases with different initial turbulent Mach numbers and Reynolds numbers.
