Additionally, a transport equation for the length scale of energy-containing eddies is introduced that allows an appropriate transition of length scale from URANS to LES mode. The modified framework is shown to trigger a transition from URANS to LES in stable attached stationary turbulent channel flow and mitigate the log-layer mismatch problem to a great extent. When applied to flows that feature boundary layer separation, i.e., flow over a periodic hill and flow over the wall-mounted hump, the current hybrid framework delivers results in agreement with existing experimental data and comparable to high fidelity LES calculations.
