Fluid flow through a helical pipe

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 $\ep $. By rigorous asymptotic analysis, as $\ep \rightarrow 0$ , the effective behavior of the flow is found. The error estimate for the approximation is proved.
