Abstract

This study aims at development of the bursting-layer model which enables us to describe correctly Reynolds stress in a non-logarithmic layer (bursting-layer) generated under the strong winds affected sea surface. The Reynolds stress in the non-logarithmic layer was separated into a low-frequency Reynolds stress that originates from the mean shear flow and a high-frequency Reynolds stress that originates from wind-wave breakers. The thickness of the non-logarithmic layer, the vertical distribution of the horizontal mean velocity, the low-frequency eddy viscous coefficient and so on were formulated to describe the low-frequency Reynolds stress and the high-frequency Reynolds stress. Furthermore, validity of both the Reynolds stress described with the bursting-layer model was verified by performing comparisons with experimental results.
