One of the important tasks associated with reducing the concentration of contaminants in the sea surface layer is the determination of their mixing volume, as of the most active systems for mixing the sea surface layer are sea vessels. The wake of a ship is a highly mixed medium. The study of the wake development over time is important when evaluating the mixing of various pollutants in the wake with neutralizing chemicals. As shown in some previous works, in the wake of a vessel that crosses a contaminated surface, the concentration of harmful impurities decreases to background values; however, the problem of determining the volumetric characteristics of this wake remains. In our work, we propose a relatively simple model for assessing the characteristics of a turbulent wake in the near zone behind a vessel. Based on the actual parameters of the vessels, the parameter F= (penetration depth) / (draft) was calculated, which characterizes the potential mixing effects caused by turbulence in the wake. The proposed simple model can be used, for example, to assess the mixing of oil when it is being bottled, with chemicals, to assess possible scenarios of increasing its dilution.

与降低海面层中污染物的浓度有关的重要任务之一是确定其混合量，因为最有效的海面层混合系统是船舶。船尾是高度混合的媒介。在评估尾流中各种污染物与中和化学品的混合时，研究尾流随时间的变化很重要。如先前的一些工作所示，在船只越过受污染的表面之后，有害杂质的浓度会降低到背景值。然而，仍然存在确定该尾流的体积特性的问题。在我们的工作中，我们提出了一个相对简单的模型来评估船只后面附近区域中湍流尾流的特征。计算出F＝（穿透深度）/（草案），其表征了尾流湍流引起的潜在混合效应。提议的简单模型可用于，例如，在瓶装油时评估油与化学品的混合，以评估增加其稀释度的可能情况。
