Localised structures in the ideal and viscous models. Wavelet study

Localized structures singled out with the use of wavelet based algorithm from the shock capturing calculations for Euler and Navier–Stokes models are analyzed. It is demonstrated that in the viscous model localized structures corresponding to the shock waves in Euler model are located with high accuracy. In the viscous model additional structures corresponding to vortices, to the boundary and mixing layers are located.
