Abstract
Compressible mixing layers have been investigated by several authors (see e.g. the reviews by Goebels & Dutton, 1990, Barre et al., 1994). Supersonic jets are less documented. However, experiments (e.g. Gutmark et al., 1991) and stability analysis (e.g. Morris et al., 1990) suggest that strong similarities exist between axisymmetric and plane mixing layers. In particular, the convective Mach number (see Papamoschou & Roshko, 1988) seems appropriate to describe the nearfield of circular compressible jets. This paper presents experimental results obtained with Pitot probes, thermocouples and a LDV system in a supersonic heated jet discharging into a supersonic coaxial flow. The convective Mach number varies from M c =0.08 to 0.6. Its effect on growth rates and on turbulence anisotropy is discussed.
