3D stationary and non-stationary non-compressible viscous flow in tubes with nonsymmetrical swelling is investigated in this paper. The finite-difference algorithms in curvilinear, non-orthogonal body fitted coordinates calculate velocity and pressure. Non-suggestion grid is used for investigation of non-stationary flows and a collocated grid - for stationary flows. A new algorithm based on the algebraic velocity expansion is applied to the collocated grid.
