Abstract

An innovative system to recover part of the energy from man-made wind resources is introduced. A vertical-axiswind- turbine (VAWT) with an enclosure is mounted above a cooling tower to harness wind energy to generate electricity. The enclosure enhances the performance of the VAWT. It is equipped with guide-vanes that guide the wind to the optimum angle-of-attack of the turbine. Besides, diffuser-plates are mounted at a specific angle to accelerate the airflow. Both laboratory test and on-site field test show no measurable difference on the outlet air speed of the cooling tower; the outlet speed of the cooling tower without and with the VAWT is 10.63 m/s and 10.67 m/s respectively (the rotational speed of the turbine is 881rpm). No difference was observed on the power consumption for both cases (7.0~7.1 kW). This system is retrofit-able to existing cooling towers and has high market potential due to abundant exhaust air resources globally.
