Numerical simulation of a supersonic flow of a viscous heat-conducting gas around the HB-2 model for various angles of attack, α = 0°, 8°, and 16°, and temperatures of the model surface is carried out based on a compact hyperbolic system of quasi

We study difference schemes associated with a simplified linearized multidimensional hyperbolic quasi-gasdynamic system of differential equations. It is shown that an explicit two-level vector difference scheme with flux relaxation for a second-order

An algorithm for solving problems of magnetic gas dynamics, which is adapted to the architecture of computing systems with extramassive parallelism, is discussed. The algorithm is based on a kinetic model that describes the dynamics of an ensemble of

The concept of a factor model based on frames is proposed. Factors are considered as slot values of the corresponding frames, which makes it possible to reduce the complexity of the developed model. The method for calculating the factor values by sea

A new numerical algorithm for solving parabolic equations by balance & characteristic difference schemes is proposed. The balance and characteristic schemes combine the advantages of conservative and characteristic schemes. The main advantage of the
