Zone locations in the spiral duct
Grahic Jump Location
Secondary flow streamlines for spiraling-outward flow at the 1080 deg slice plane: (a) γ=8, Re=100; (b) γ=8, Re=500. Only the upper half of the duct cross section is shown above the symmetry plane

Stability diagram in the Dean-number–curvature-ratio plane for curved and spiral ducts for outward-spiraling flow (adapted from 23)
Grahic Jump Location
Variation of the peripherally averaged local Nusselt number for outward-spiraling flow with Dean number for γ=8, Pr=0.7 and 5, and Re=100, 300, and 500
Grahic Jump Location
Variation of local Nusselt number with streamwise distance along the centerline for γ=8 and spiraling-outward flow
Grahic Jump Location
Comparison of present correlations for average Nusselt number (Pr=0.7) versus average Dean number with those of previous studies (boundary conditions: H1 is constant axial wall heat flux and constant peripheral wall temperature, H2 is constant axial wall heat flux and constant peripheral wall heat flux)
