论文摘要
本说明的目的是为在强风条件下阻力系数饱和提供理论上的解释。所考虑的流体动力学模型考虑了水面上方的薄层中空气液滴水的重要影响，在水面上方有效地表现为水和空气之间的不同液体。在此层上方，该模型与对数的对数轮廓相结合，以吹出海上的强风。控制阻力系数行为的主要基础机制是水面上的毛细管波和沿中间界面剪切应力的连续性的开尔文·赫尔姆霍尔茨不稳定性。
The goal of this note is to provide a theoretical explanation for the saturation of the drag coefficient in strong wind conditions. The hydrodynamic model under consideration takes into account the important effects of airborne droplets of water in a thin layer above the water surface that effectively behave as a different fluid between the water and the air. Above this layer the model is coupled with a log-wind profile for the strong winds blowing above the sea. The main underlying mechanism governing the behavior of the drag coefficient is the Kelvin Helmholtz instability for capillary waves on the water surface and the continuity of shear stress along the intermediate interface.
