heal.abstract	The paper describes the development and application of a computational procedure for calculating the velocity field in fully-developed flow through spirally fluted tubes. Topics covered include the choice of coordinate system, the resultant form of the governing equations, the validation of the accuracy of the procedure by comparison with known analytical solutions and a discussion of the results of applying the procedure to the spirally fluted tube flow itself. The computations indicate that the effectiveness of the flutes in imparting swirl to the flow increases markedly with the number of flutes. The swirling motion and the turning over of fluid within the flute region produces very little increase in drag; indeed, when friction factor and Reynolds number are based on hydraulic diameter, the drag is less than for a smooth tube. © 1984.	en
