Abstract Oscillating boundary layer flow over an infinite flat plate at rest was simulated using the k – k L – ω turbulence model for a Reynolds number range of 32 ⩽ Re δ ⩽ 10,000 ranging from fully laminar flow to fully turbulent flow. The k – k L – ω model was validated by comparing the predictions with LES results and experimental results for intermittently turbulent and fully turbulent flow regimes. The good agreement obtained between the k – k L – ω model prediction with the experimental and LES 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.
