Abstract

It is well known that for viscoelastic fluids, rectilinear flow through pipes of non-circular cross-section is not possible in general and some secondary flows appear in the cross-section of the pipe. These secondary flows have a strong effect upon the flow characteristics but do not influence appreciably the rate of flow through the pipe. (1). Nevertheless it has been shown that the secondary flows improve substantially the heat transfer properties along the pipe when compared to pipes of equivalent circular cross-section (2,3,4,5)
