Abstract: | In this paper we study the flow of incompressible Newtonian fluid through a helical pipe with prescribed pressures at its
ends. Pipe’s thickness and the helix step are considered as the small parameter ɛ. By rigorous asymptotic analysis, as ɛ→
0 , the effective behaviour of the flow is found. The error estimate for the approximation is proved. |
