We present application of the hybrid two-level large-eddy simulation method; a multi-scale model for simulation of high Reynolds number turbulent flows.1 The method combines the two-level simulation model2 with a conventional large-eddy simulation model in an additive manner through a normalized blending function. The original implementation of the method was specialized as a near-wall model with the use of a step function based blending, where the two-level simulation model was used to resolve the near-wall turbulence dynamics and large-eddy simulation was used in the far-away region.1 The method has been further improved by incorporating a general form of blending function, development of a scale-similar closure model and enhancement in the computational efficiency.3 Here, we present application of the enhanced method to study instantaneous flow features and turbulence statistics in three canonical configurations that include a fully developed turbulent flow in a channel, a weakly separating/reattaching flow over a bump and flow past a circular cylinder at a sub-critical Reynolds number. We demonstrate the accuracy, efficiency and predictive ability of the method by comparing results for characteristic flow features and turbulence statistics with previously reported experimental and numerical results.
