Abstract
Abstract An oscillatory boundary layer flow with a flat-crested freestream velocity profile and a steep pressure gradient over an infinite flat plate at rest was simulated using the k – k L – ω turbulence model. The simulations were conducted for a Reynolds number range of 32 ⩽ Re δ ⩽ 10,000 that spans from fully laminar flow to fully turbulent flow. The k – k L – ω model was validated by comparing the predictions with DNS results for the intermittently turbulent flow regime. The good agreement obtained between the k – k L – ω model prediction with the DNS results indicate that the k – k L – ω model is able to accurately simulate transient intermittently turbulent flow and as well as accurately predict the onset of turbulence for such oscillatory flows.
