Abstract: | In this paper, we study the numerical solution of the Stokes system
in deformed axisymmetric geometries. In the azimuthal direction the
discretization is carried out by using truncated Fourier series,
thus reducing the dimension of the problem. The resulting
two-dimensional problems are discretized using the spectral element
method which is based on the variational formulation in primitive
variables. The meridian domain is subdivided into elements, in each
of which the solution is approximated by truncated polynomial
series. The results of numerical experiments for several geometries
are presented. |
