Abstract

Direct Numerical Simulations of the idealized interaction of a normal shock wave with several turbulent shear flows are conducted. We analyse the behaviours of velocity and vorticity fluctuations and compare them to what happens in the isotropic situation. Investigation of the budgets of these quantities allows to isolate the mechanisms underlying the physics of the interaction, and reveals the importance of enthalpic production and baroclinic torque in such flows.
