Abstract
A recently developed analysis of the laminar mixing of two steady two-dimensional flows is subjected to a comparison with two different sets of experimental data. The theory considers the mixing beyond the trailing edge of a thin partition, accounts for the initial boundary layers, and allows broad dissimilarities in the two Mach numbers and total temperatures. Earlier comparisons produced good agreement between this theory and numerical and experimental results for wakes and base flows. In this paper, the theory is compared with the measured flowfield of a mixing layer separating two isothermal streams at nominal Mach numbers 3 and 2.3. A second experiment is also reported here, in which a Mach 8 flow merges with a colder Mach 3 stream. In both cases the agreement between theory and experiment is satisfactory. a a ' b ' Cn M Mc Me P ' Re ' Reei ReXr S
