Abstract: In numerical modeling of continuum flows with shock waves the discontinuity surface is as usual replaced by transition layer of a finite width (discontinuity distraction) which depends on both the used method and the type of discontinuity. A specified method is proposed to study discontinuity distraction for numerical techniques used to solve the hydrodynamics equations. This method allows to determine the distraction of shock waves of arbitrary intensity. A term “effective distraction” is introduced and distraction and effective distraction for Neumann–Richtmayer, Lax, Godunov and Kuropatenko techniques are studied.
