Abstract

This work is devoted to investigation of the self-similarity behavior of the stably thermostratified air turbulent boundary layer above the wavy surface for a wide range of wind speed and wave state parameters. Experiments were carried out on the TSWiWaT facility with special system of wave damping using underwater plastic net which allowed to adjust the wave parameters independently on the wind speed. It was shown that the profiles of the velocity defect and the temperature defect in the turbulent airflow boundary layer near water surface are self-similar. Besides, for both velocity and temperature the form of self-similarity profiles did not depend on parameters of surface roughness, but only depend on the wind speed.
