“…Our linear analysis validates an idea that the blast wave can amplify both density and vorticity perturbations in the turbulized interstellar medium through reso- nant shock-turbulence interaction. This result is consistent with analytic and numerical studies (Lee et al 1997;Jamme et al 2002;Wouchuk et al 2009) predicting vorticity amplification by a distorted shock front. As distinct from the aforementioned works we study the nonlocal mechanism of amplification when the wave lengths λ of perturbations are not negligible compared with the shock wave size R s .…”

“…The possibility of turbulence amplification by the shock waves has been a debatable issue for a long time. Such a possibility has been proved theoretically (Wouchuk et al 2009;Donzis 2012), numerically (Lee et al 1997;Balsara et al 2001;Jamme et al 2002) and experimentally (Andreopoulos et al 2000).…”

“…Mahesh et al 4 considered the influence of entropy fluctuations on the upstream turbulence and found that negatively correlated velocity and temperature fluctuations lead to enhanced amplifications of turbulence kinetic energy and vorticity. Later, Jamme et al 5 resolved the viscous shock structure at Mach 1.2 and 1.5, and essentially confirmed the findings of Mahesh et al Barre et al 6 studied the problem experimentally in a wind tunnel and measured the velocity variances using hot wires and laser Doppler velocimetry.…”

“…We check the efficacy of the new modification introduced in the k-⑀ model by comparing its prediction with DNS data of shock/homogeneous turbulence interaction. 10,12 Of the three cases listed in Table I, the first two are at Mach number 1.29 and the third case is at Mach number 1.5. Case 1.29A has essentially vortical inflow turbulence, while cases 1.29B and 1.5 have an entropic thermodynamic field along with a vortical velocity field upstream of the shock.…”
