Steady-state flow of an incompressible viscoelastic polymer fluid between two coaxial cylinders

详细

A boundary value problem for a quasi-linear equation determining the velocity profile of a flow of a polymer fluid in a pipe formed by two coaxial cylinders is considered. On the basis of methods of approximation without saturation, a computational algorithm of increased accuracy is developed, making it possible to solve the problem in a wide range of parameters, including record-low values of r₀, the radius of the inner cylinder.
