The Viscous Flow in a Channel with Helical Fins

摘要

The paper suggests using a helical coordinate system for numerical simulation of viscous flow in a channel with helical fins. A mathematical model was implemented in the package Comsol Multiphysics. The influence of four tins on the flow structure is analyzed. As a summary it is presented the dependency of darcy friction factor to Reynolds number for the pitch of screw fins S/D=3, 4,5.
