Performance Evaluation of Axial Flow Wind Turbine Integrated with The Condenser

Abstract

This study investigated the application of an axial flow wind turbine integrated with a condenser. The exhaust air from condenser was used to drive the wind turbine by a ducted turbine system. There were two parameters varied in this work: the blade number and the blade pitch angle. The blade number used was two blades, five blades, and ten blades, while the blade pitch angles were 5°, 10°, 15°, 20°, 30°, and 45°. The diameter of the wind turbine was 495 mm. The model of the condenser had a fan diameter of 600 mm and the range of the average air velocity of 2.01 m/s - 7.86 m/s. The maximum mechanical power was 10.72 W for air velocity of 7.86 m/s. The maximum power coefficient recorded was 0.38 for the tip speed ratio of 1.3 on the blade number of five blades and a pitch angle of 10°. The maximum exhaust air energy recovery was 13.64% of the power consumption of the condenser fan.

Study On the Potentiality of Power Generation from Exhaust Air Energy Recovery Wind Turbine: A Review

“…The experiment results show the higher power coefficient is reached when the gap was 2.5D on the upstream and downstream turbine with Cp of 0.122 and 0.082 respectively. Findings by Santoso et al, [28] shows that by increasing the starting torque value enables the wind turbine to spin at lower wind speeds in order to generate electricity early on. As a result, the cut-in speed value of the axial flow wind turbine would be decreased by rising blade numbers.…”
