Compressibility effects on the transition to turbulence in a spatially developing plane free shear layer

Compressibility effects on energy exchange mechanisms in a spatially developing plane free shear layer

“…For the detailed description of the boundary conditions, we refer to our previous work (Li et al. 2019) – hereinafter referred to as ‘part I’.

“…The configuration of the splitter plate is illustrated in figure 1 (for the detailed description of the FSL initial conditions, readers are referred to Li et al. (2019)).…”

“…Consequently, a small perturbation is superimposed on the upper boundary layer (Li et al. 2019). This perturbation allows a realistic initial development of disturbances, ensuring a naturally developing destabilization in the boundary layer at the trailing edge of the splitter (Laizet et al.…”

“…The Reynolds numbers of the two inlet boundary layers are (based on and ) and (based on and ), respectively (Li et al. 2019). Here, is the initial momentum thickness of the lower boundary layer (low-speed side), and is evaluated just upstream of the trailing edge.…”
