Effect of upstream velocity profile on the free mixing of jets with ambient fluid

Research output: Contribution to journalArticle


The asymmetric jet created by the mixing of a wall jet with quiescent surrounding fluid downstream of a trailing edge is considered. The method of analytic continuation developed by Goldstein is extended to provide a series solution for the asymmetric jet. The different boundary conditions as well as the extension to turbulent flow reveal some new aspects that are discussed in detail. In particular, the conservation of momentum downstream of the trailing edge enables one to determine the location of a jet with respect to the y coordinate. In turbulent flow the analysis has been supplemented by experiment, providing a fair agreement between the two.
