Abstrakt

The effect of a developing secondary flow, induced by both centrifugal and buoyancy forces, on heat transfer inside a horizontal curved pipe is studied. The governing equations are solved in a finite element formulation using triquadratic elements for the velocity as well as for the temperature field.
Due to interaction of centrifugal, buoyancy and pressure forces, a complex secondary flow develops, consisting of two secondary longitudinal vortices, perpendicular to the axial flow. Heat transfer shows to be increased considerably as a result of the three-dimensional flow field.
