Friction and heat transfer in the swirl flow of water in an annulus
R. A. Seban,A. Hunsbedt +1 more
TL;DR: In this article, the authors measured friction and heat transfer on an annulus in which swirl flow of water was produced by a single helical vane and showed that the friction and the heat-transfer coefficients for turbulent flow can be predicted by the appropriate adjustment of available values for straight channels.

Heat transfer in curved and straight channels with transitional flow
C. R. Hedlund,Phil Ligrani +1 more
TL;DR: In this paper, heat transfer in a channel with a straight portion followed by a portion with mild curvature is studied at Dean numbers from 300 to 750, where the channel aspect ratio is 40, radius ratio is 0.979, and the ratio of shear layer thickness to channel inner radius was 0.011.

Note on the motion of fluid in a curved pipe
W. R. Dean,J. M. Hurst +1 more
TL;DR: In this paper, it is assumed that the actual secondary motion is replaced by a uniform stream; conditions in the central part of the section mainly determines the motion and the appropriate velocity of the stream can be determined from the relation that has been found experimentally between the rate of flow in a curved pipe and the pressure gradient.
