Aeration is a critical process of commercial aquaculture and is required for maintaining sufficient dissolved oxygen (DO) levels for producing high yields of fish. However, many producers in low-income countries do not use active aeration due to high costs or lack of electrical availability. This project optimizes the design of a wind-powered system for passively increasing DO concentration in aquaculture ponds for use in these regions. The design consists of a vertical-axis wind turbine coupled to a subsurface impeller positioned in a draft tube. CFD-based optimization experiments were conducted to maximize the turbine efficiency and to increase the rate of water circulation. The optimized system was tested in an aquaculture pond to evaluate the impact of the system on DO levels. The optimized aeration system operated at a 12% greater rotational speed than the original design, improved distribution of DO and elevated the overall concentration by an average of 18%.
