Abstract

Secondary flows in curved rectangular ducts with diminishing cross sections are numerically studied. Development of secondary flow in curved rectangular regular cross-sectional area duct is studied using an improved finite difference scheme for solving parabolized Navier-Stokes equations is presented. This scheme has its origin in the work of Briley, which is based on classical ADI method to march the solution in the streamwise direction. With some modifications, it is shown in the present work that the stability of this scheme is greatly enhanced. Its applicability is considerably increased. Results with various sb. and sa for two different aspect ratio are given. Note the parameters asa and bsb, where s a is scaling factor for the width of the duct sb is scaling factor for the height of the duct, respectively. Dean number of 54 is used for the comparisons.
