Grahic Jump Location
(a) The curved tube coordinates (r,θ,s). The direction s is along the center line. (b) Axial cross section showing two fluid regions and the blunted velocity profile.
Grahic Jump Location
Typical velocity profiles (δ=0.1,α=3.2,θ=0). The first-order correction w1 due to curvature is anti-symmetric.
Grahic Jump Location
The flow rate as a function of δ. (α=3.317).q0 is for the straight tube, q2 is the correction due to curvature.
