Keywords:

twirled flow; stability; method of solving


Abstracts:

The new method of the solution of a problem of stability of the twirled flow of viscous incompressible liquid is developed. The method based on decomposition of functions abreast on extents of the radial coordinate, allows to avoid the difficulties connected with a numerical integration of system of the differential equations with singular point. As example the stability of Poiseuille flow in a rotating pipe is studied
