摘要：

We study the flow of a heat-conducting incompressible Newtonian fluid through a helical pipe with cooling. The pipe's thickness and the helix step are considered as the small parameter epsilon. Using asymptotic analysis with respect to epsilon, we derive the simplified mathematical model describing the heat transfer through the pipe. The error estimate for the approximation is proved.
