Abstract

A cross flow wind turbine was positioned at the discharge outlet of a cooling tower to harness the discharged wind for electricity generation. The integration consists of guide vanes and diffuser plates is used to enhance the rotational speed of the turbines for power augmentation. The number and angle of the guide-vanes is optimized to ensure the oncoming wind stream impinges the rotor blades of the turbine at an optimum angle. To avoid a negative impact on the performance of the cooling tower and to optimize the turbine performance, the determination of the turbine position in the discharge wind stream was also conducted by experiment. The preferable position is where the higher wind velocity matches the positive torque area of the turbine rotation. The performance of the system is tested in the laboratory using scaled down model. The turbine performance is increased in the range of 22.21–67.33 % with the guide vanes. With the proper matching among the guide vanes configurations and exhaust air velocity profile, the turbine system was not only able to recover the wasted kinetic energy, it also reduced the fan motor power consumption by 2.46 %.
