On properties of a semi-explicit in time fourth-order vector compact scheme for the multidimensional acoustic wave equation
Alexander Zlotnik, Timofey Lomonosov
We deal with an initial-boundary value problem for the multidimensional acoustic wave equation, with the variable speed of sound. For a three-level semi-explicit in time higher-ord…

On a Doubly Reduced Model for Dynamics of Heterogeneous Mixtures of Stiffened Gases, its Regularizations and their Implementations
A. Zlotnik, T. Lomonosov
We deal with the reduced four-equation model for the dynamics of heterogeneous compressible binary mixtures with the stiffened gas equations of state. We study its further reduced…
