Abstract : The problem of turbulent mixing between two compressible streams in a constant duct area and with eccentric primary flow jet is analyzed. A theoretical analysis is presented for the velocity profiles. It was found that these profiles with or without eccentricity are almost the same if they are referred to the axis of the primary flow jet. An experimental investigation for the case of eccentricity ratio (e/R) equal to 0.25, given area ratios 3 and 7.16 and with a velocity ratio ranging from 1.2 to 2.9 was performed. The theoretical analysis shows good agreement with the experimental results, especially for cases with high area ratios and with low velocity magnitudes. (Author)
