Abstract
This article considers the extension of the multilayer hydrostatic CABARET-MFSH model to the case of three spatial variables. The model describes the dynamics of a fluid with a variable density and a free surface. The hyperbolic decomposition algorithm gives a representation of the matrix of the system as a product of 4 × 4 matrices, the eigenvalues of each of which are always real. An explicit CABARET scheme is used to solve the system of hyperbolic equations in each layer. To validate the model, the problem of a three-dimensional fluid flow with variable density is used. The numerical calculations are in satisfactory agreement with the experimental data.
