Wall shear-stress statistics for the turbulent boundary layer by use of a predictive wall-model with LES
نویسندگان
چکیده
Time-wise velocity signals obtained from large-eddy simulation (LES) within the near-wall, logarithmic region of the zeropressure gradient, flat-plate turbulent boundary layer are used as input to a calibrated, empirical wall model to calculate the statistics of the fluctuating, wall shear stress τw. The results, together with those from numerical simulation and experiment indicate a log-variation of (τ′+ w )2 with increasing Reτ.

The efficacy of large-eddy simulation ~LES! with wall modeling for complex turbulent flows is assessed by considering turbulent boundary-layer flows past an asymmetric trailing-edge. Wall models based on turbulent boundary-layer equations and their simpler variants are employed to compute the instantaneous wall shear stress, which is used as approximate boundary conditions for the LES. It is de...

متن کاملTurbulent Drag Reduction by Spanwise Wall Oscillations
The objective of this paper is to examine the effectiveness of wall oscillation as a control scheme of drag reduction. Two flow configurations are considered: constant flow rate and constant mean pressure gradient. The Navier-Stokes equations are solved using Fourier-Chebyshev spectral methods and the oscillation in sinusoidal form is enforced on the walls through boundary conditions for the sp...
