An extensive experimental investigation has been performed of the mixing behavior of incompressible co-annular air streams with substantial swirl present in the inner stream. Four sets of experiments were performed and each set corresponded to a different configuration of the test section. The test section configuration of each of the four sets of experiments were free annular swirling jet, annular swirling jet with a centerbody, co-annular streams with swirl present in the inner stream and with a centerbody, and co-annular streams with swirl present in the inner stream and with a constant-area annular duct test section. The experimental investigation determined the behavior of the mean flow profiles at several axial locations for the four sets of tests with the most extensive investigation performed in the fourth set of tests.
