Exergoeconomic analysis of ejector-augmented shrouded wind turbines

A detailed exergoeconomic analysis of an ejector-augmented shrouded horizontal axial wind turbine at three ejector inlet area ratios was conducted. Key exergoeconomic parameters examined include, cost rate of the power produced, exergy loss to cost rate, exergetic improvement potential, power produced, and air mass flow rate through the wind turbine. The findings demonstrate that the performance of the wind turbine improves as the ejector inlet area ratio increased, and the cost per kWh of the power produced decreases significantly with wind speed increased from about 2 $/kWh at 5 m/s to about 0.1 $/kWh at 15 m/s. On the other hand, the exergy destruction rate is relatively low while the exergy loss is relatively high.
