Abstract: The paper is devoted to the problems of solvability in Sobolev classes of the boundary value problem for a two-dimensional system of Navier–Stokes equations in a non-cylindrical domain represented by a truncated cone. A special basis consisting of eigenfunctions of one spectral problem is constructed. Using the methods of a priori estimates and Faedo–Galerkin, we prove theorems about the existence and uniqueness of the solution to the boundary value problem under consideration, and its regularity with increasing the smoothness of the given functions.
