Abstract
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
