  Viscous incompressible flow in pipes of variable cross sections is considered with a view to physiological conditions. Steady and oscillatory inlet flow conditions are discussed. Asymptotic solutions of the basic equations, with respect to inherent parameters, are given.· Weakly non-linear .effects are included. The predicted flow fields are generally in accordance with observations.

  Oscillatory flow in U-shaped pipes have been investigated experimentally. The velocity field is mapped by observing the motion of tracer particles either photographically or by Laser Doppler Anemometry. The most important result seems to be the observation of regions with strong secondary streaming at the inlet of the curved section, which, to the best of our knowledge, have not been reported before,

  The general homogeneous solution of the differential equation associated with an arbitrary term of the Blasius series expansion of the stream function, is given. This result is used to establish the solution of higher order terms of the Blasius series, than earlier published. A numerical .example is also given.
