Abstract: |
In this paper,in order to take the numerical simulation of fully developedviscous flow in a rotating rectangular duct,numerical algorithm MAC-AFl is employedto solve primitive incompressible unsteady Navier-Stokes equation.The numerical results contain secondary flow structures and velocity profiles along the horizontal centreline and the vertical centreline of the duct,existing experimental with numerical resultsis quite favourable. |
