Abstract

In this study we present an alternate development of a non-orthogonal coordinate system that is useful in studying the limit of large pitch. It is based on a rotating cartesian system of coordinates. A square cross-section has been considered for the tube. An analytical solution has been obtained for the large pitch limit. For smaller pitch values, the complete Navier-Stokes equation has been solved numerically. At higher Reynolds number, the axial velocity profile shows a shift towards the outer wall which is in qualitative agreement with earlier results obtained for zero pitch limit. However, the secondary velocity profile shows a markedly different behavior. The twin-counter rotating cells that are found in the zero pitch case is absent for the finite pitch case.
