Analysis of shock-wave diffraction over double cylindrical wedges. Part II: Vorticity generation
TL;DR: In this article, the effect of the first concave surface on the shock strength has been quantified at both earlier and final stages of the shock diffraction process, and the results show that the diffusion of the vorticity due to viscous effects is quite important compared to the baroclinic term for low Mach numbers regimes.
Turbulent structures of shock-wave diffraction over 90° convex corner
TL;DR: The turbulent structures and long-time flow dynamics of shock diffraction over 90° convex corner associated with an incident shock Mach number Ms = 1.5 are investigated by large eddy simulation (LES) as mentioned in this paper.
Analysis of shock-wave diffraction over double concave cylindrical wedges. Part I: Shock dynamics
TL;DR: In this article, a mesh-independent solution is obtained and the flow is assessed through different physical quantities (transition angles, triple points trajectories, wall-pressure and skin-friction distributions, velocity and shock location).
