circular cross-section were investigated by employing a perturbation method. A perturbation
solution up to the second order was obtained for a small curvature ratio, K. The variations of
axial velocity distribution and secondary flow structure with F, Re and We were discussed in
detail in order to investigate the combined effects of the three parameters on flow structure.
The combined effects of the Coriolis force, inertia force and elastic force on the temperature …
