ملخص

An experimental and numerical study has been conducted to investigate the properties of irregular wave boundary layers on a rough bottom. Detailed measurement of velocity profiles was done using 1D Laser Doppler Anemometer. It was observed that the turbulence might persist under a free-stream Reynolds numbers within laminar range. The original version of k - ω odel and two versions of two-layer k - ω models have been used to predict the boundary layer properties under experimental conditions. It was found that the model could reproduce the shear stress variation in time quite successfully but the magnitude could not be predicted adequately. This discrepancy may partly be due to the estimation of the shear stress from the velocity data by log-law.
