Abstract

Some mathematical models are presented for viscous fluid flows in axisymmetrical channels with complicated shapes. The models differ in their complexity level. Assumptions are considered to simplify these flow models. Comparative analyses are carried out for various computational algorithm features caused with coordinate transformations, grid generations, sampling and solving of linearized multigrid equations. A detailed description of used computational algorithms is given.
