Method of Integral Relations for curved compressible turbulent mixing layers with lateral divergence
Abstract
A method is presented for predicting the development of mixing layers subjected to extra strain rates. The calculations are performed using an adaptation of the Method of Integral Relations, in which one strip is used and the velocity profile is approximated by an exponential function. A modified version of the Prandtl-Goertler eddy-viscosity model is used, which takes into account the effects of upstream conditions and the extra strain rates due to curvature, lateral divergence and mean flow dilation. Results are presented showing the development of mixing layer width and maximum shear stress.
