Abstract : Compressible rotational flows in curved ducts due to inlet total pressure gradients are analyzed. Two different time-marching methods are briefly presented and utilized for the analysis of the development of 3D flows. The former is a finite volume explicit method, the latter is a finite difference implicit method. These methods are successfully compared each other and with other methods. A first analysis of secondary flows concerning constant section curved ducts with a curvature of 90 deg is carried out.
