Effect of Torsion in a Helical Pipe Flow

Abstract

The problem of fully developed steady viscous incompressible flow in a helical pipe is studied. The predicted analytical expression in the literature for the flow rate is improved. The present result shows a reduction in the flow rate with increasing torsion, for a given curvature. Qualitatively this effect of torsion is seen to cause equivelocity contours in the normal section of the pipe, to undergo shear. © 1994, Hindawi Publishing Corporation. All rights reserved.
