概要
- 論文の詳細を見る
Numerical analysis was made of a fully-developed laminar flow in curved pipes of square cross-section under conditions wherein an oscillatory component of flow was superimposed on a steady mean flow. Velocity profiles, stream lines of secondary flow and distribution of wall shearing stresses were calculated in a wide range of various parameters, i.e. mean Dean number D^^-, Womersley number α and flow rate ratio η. It was found that one to four pairs of vortices were induced in the cross section in a cycle at moderate values of α. The kinetic energy of the secondary flow and the resistance factor were described.
