Coordinate generation method for flows through periodic channels
Abstract
A coordinate generation method for channel flows has been developed. An arbitrary channel, with boundaries consisting of straight elements in the physical plane, is mapped into a straight channel in the computational plane. Transformation is given separately for the periodic and non-periodic configurations. The parameters of the transformations have to be determined through successive approximations. A simple iteration scheme, that converges quite rapidly even with a poor initial guess, is presented. Solutions for different configurations are displayed to illustrate the capabilities of the method. The extension of the method, that includes channels consisting of curved elements, is also available.
