Abstract
A standard Galerkin finite element penalty function method is used to approximate the solution of the three-dimensional Navier-Stokes equations for steady incompressible Newtonian entrance flow in a 90 " curved tube (curvature ratio 6 = 1/6) for a triple of Dean numbers (K = 41,122 and 204). The computational results for the intermediate Dean number (K = 122) are compared with the results of laser-Doppler velocity measure-ments in an equivalent experimental model. For both the axial and secondary velocity components, fair agreement between the computational and experimental results is found.
