| Abstract | In this paper, a numerical study is presented for the fully developed two-dimensional flow of viscous incompressible fluid through a curved rectangular duct. The outer wall of the duct is heated while the inner one is cooled. Numerical calculations are carried out by using the spectral method covering a wide range of the Dean number,Dn , 0 ⤠Dn ⤠1500 and the curvature, δ , 0 n is increased no matter what δ is. Effects of curvature on the unsteady solutions are also obtained. The transition to the periodic or the chaotic state is retarded, if the curvature is increased. |
