Industrial fish farms rely on aerators for multiple purposes, including the oxygenation of water and the isolation**of fish from plankton blooms. Poseidon Ocean Systems Ltd, an aquaculture solutions and technology company,**seeks expertise in computational fluid dynamics (CFD) to run numerical simulations and analyze the behaviors**of current aerators and then improve the designs. Several critical aspects of aerators need to be studied,**including water entrainment by an aerator, optimizing the geometry and locations of aerators in a farm, and**effects of the ambient water current on the performance of the aerators. With a collaboration between Poseidon**Ocean Systems Ltd and Memorial University, this project aims to develop numerical simulation tools and data**to better understand these problems. Multiphase flow models will be used to predict the flow from one aerator,**and subsequently, from an array of aerators. The results will be used by the company in improving design and**operation for better performance of the aerators and the water quality in fish farms. There will also be**significant environmental benefits since a reduction in fuel consumption will result in a reduction of pollution.

工业化养鱼场依靠曝气器实现多种目的，包括水的氧化和鱼类与浮游生物的隔离。Poseidon Ocean Systems Ltd是一家水产养殖解决方案和技术公司，** 寻求计算流体动力学（CFD）方面的专业知识，以运行数值模拟并分析当前曝气器的行为 **，然后改进设计。需要研究曝气器的几个关键方面，** 包括曝气器的水夹带，优化农场中曝气器的几何形状和位置，以及 ** 环境水流对曝气器性能的影响。通过Poseidon**Ocean Systems Ltd和纪念大学的合作，该项目旨在开发数值模拟工具和数据 **，以更好地了解这些问题。多相流模型将用于预测一个曝气池的流量，** 以及随后一系列曝气池的流量。研究结果将用于该公司改进设计和操作，以提高曝气器的性能和养鱼场的水质。由于燃料消耗的减少将导致污染的减少，因此也将产生重大的环境效益。
