Abstract
High Reynolds number compressible free shear layers were studied experimentally to explore the effects of compressibility on the turbulence field. Previous preliminary results reported by the authors showed that the level and the lateral extent of turbulence fluctuations are reduced as the compressibility, which is characterized by a convective Mach number, In the present work both range of convective Mach earlier work have been reduction in both level extent of turbulence fluctuations with increasing M which was reported earlier for Mc of 0.51 and 0.64 is much higher at Mc of 0.86. The higher order moments of turbulence fluctuations such as skewness and flatness are reported which show that the intermittency due to the excursion of large scale structures into the free streams at the edge of shear layers was significantly reduced (both in the level and the extent) due to increased Mc. In the developing region of shear layers, development of mean flow and turbulence fluctuation profiles are reported which have similar trends seen in incompressible shear layers.
