Abstract:
The flow in a rotating curved pipe with circular cross section is investigated theoretically and numerically. A perturbation solution up to the second order is obtained. A numerical procedure is used to solve the full governing equations and the simplified governing equations in the small curvature limit. Comparisons are made between the numerical and perturbation results, elucidating the lost information due to simplification and the valid range of the perturbation solution. The flow characteristics, including the secondary flow, the axial flow, and the friction factor ratio, are examined in detail.
