Open (deep) cavities in aerodynamic structures contain highly turbulent and acoustic flow fields because of the aft wall impingement of the shear-layer that separates from the upstream edge of the geometry. Although delayed detached-eddy simulation is a promising approach for massively separation regions, it could not capture the whole turbulent field due to its major drawback, the delay of transition to large-eddy simulation mode in the shear-layer. This study enhances the results around the separation region with the use of "shear-layer-adapted" length scale from literature which ensures the rapid transition from modeled to resolved mode of delayed detached-eddy simulation.
