Abstract: We justified the integral convergence method for studying the accuracy of finite-difference shock-capturing schemes in the numerical simulation of shock waves propagating at variable speed. For this, the order of integral convergence is determined using a series of numerical calculations on a family of nested difference meshes, which makes it possible to simulate a space-continuous difference solution of the corresponding Cauchy problem. This approach is used to study the accuracy of the explicit difference schemes of Rusanov, TVD and WENO, having a higher order of classical approximation, as well as an implicit compact scheme with artificial viscosity of the fourth order of divergence, which has the third order of both classical and weak approximations.
