摘要

本文基于数值和实验方法研究了污损网面板的流体力学和周围流场特征。分析了污损网面板的类型，并根据污染物的附着位置和形态特征将其分为贝壳聚集污损网和生物累积污损网。每种污损网板的物理模型都是手工制作的，用于水槽实验。利用大涡模拟法建立相应的数值简化模型，进行流场模拟，计算分析网的流体力学，捕捉污染物引起的流场细微变化，量化分析每种水生污损网的渗透性。

Numerical and experimental study of two common types of fouled net panels in the ocean

In this paper, the hydrodynamic and surrounding flow field characteristics of fouled nets panel are studied based on numerical and experimental methods. The types of fouled nets panel are analyzed and be divided into shell aggregation fouled net and bio-accumulation fouled net according to the attachment location and morphological characteristics of contaminants. Physical models of each type of fouled nets panel are made manually for water tank experiments. The corresponding numerical simplified model was established using the large eddy simulation method for flow field simulation to calculate and analyze the hydrodynamics of the net, capture the subtle changes in the flow field caused by pollutants, quantify and analyze the permeability of each hydroid-fouled nets.

期刊介绍： Aquacultural Engineering is concerned with the design and development of effective aquacultural systems for marine and freshwater facilities. The journal aims to apply the knowledge gained from basic research which potentially can be translated into commercial operations. Problems of scale-up and application of research data involve many parameters, both physical and biological, making it difficult to anticipate the interaction between the unit processes and the cultured animals. Aquacultural Engineering aims to develop this bioengineering interface for aquaculture and welcomes contributions in the following areas: – Engineering and design of aquaculture facilities – Engineering-based research studies – Construction experience and techniques – In-service experience, commissioning, operation – Materials selection and their uses – Quantification of biological data and constraints
