Abstract
The development of complex velocity fields in curved ducts from an initially parabolic profile was studied using a three dimensional numerical model of the parabolized Navier-Stokes equations. The velocity profiles were influenced strongly by a geometrical parameter (the radius of curvature) and a dynamic parameter. Numerical results are presented for flow through curved ducts with periodic step changes in curvature.
